The correct chronological sequence is: 1. Establishment of the Delhi Sultanate (1206) 2. Establishment of Vijayanagara Empire (1336) 3. Foundation and rise of the Gajapati kingdom in Orissa (14th–15th century context) 4. Arrival of the Portuguese on the west coast (1498) Thus Option B correctly reflects the historical timeline.

Statement 1 is incorrect because Vijayanagara was founded by Harihara and Bukka, not Colin Mackenzie. Statement 2 is also incorrect because the empire contained people speaking different languages and following different religious traditions. Its frontiers were fluctuating rather than permanently fixed. Therefore, neither statement is correct.

The Assertion is true because the memory of Vijayanagara survives through the ruins at Hampi. The Reason is also true because Hampi is derived from Pampadevi, the local mother goddess. However, the derivation of the name Hampi does not explain why the memory of the empire survived there. The memory survived because the capital city and its ruins were located at Hampi. Therefore, both statements are true, but R is not the correct explanation of A.

The Vijayanagara rulers built upon existing traditions of temple construction established by earlier dynasties such as the Cholas, Hoysalas, Chalukyas, and Pandyas. By sponsoring elaborate temples and religious institutions, they legitimized their authority and strengthened political integration. Therefore, Option C is correct.

The correct matching is: 1 → b (Gajapati rulers → Orissa) 2 → c (Cholas → Tamil Nadu) 3 → d (Hoysalas → Karnataka) 4 → a (Sultans → Deccan) This corresponds exactly to Option C.

The passage explicitly states that the Vijayanagara kings and the Gajapati rulers competed for control of fertile river valleys and the resources generated by lucrative overseas trade. These regions were economically valuable because they supported agriculture, commerce, and political power. Therefore, Option B directly reflects the information given in the passage. Options A, C, and D are not mentioned as reasons for the rivalry and are not supported by NCERT.

The passage clearly states that interaction among Vijayanagara, the Deccan Sultanates, and the Gajapati rulers led to the sharing of ideas, particularly in architecture. This explains the emergence of architectural styles showing influences from different cultural traditions. Political competition and cultural exchange occurred simultaneously. Therefore, Option A is correct.

The Saluvas were military commanders who replaced the Sangama dynasty in 1485. Later, in 1503, the Tuluva dynasty succeeded the Saluvas and became the dominant ruling family. Thus, Option D correctly fills the blank.

Krishnadeva Raya's reign is remembered as the most successful period in Vijayanagara history. It was marked by military victories, territorial expansion, administrative strength, literary patronage, and economic prosperity. Option B is therefore incorrect because it directly contradicts NCERT's description of his reign. Options A, C, and D are historically supported by NCERT.

In Amuktamalyada, Krishnadeva Raya advised rulers to treat foreign merchants well, grant them profits, and provide regular audiences. His objective was to ensure a steady supply of valuable military resources such as horses and elephants and prevent these resources from reaching rival kingdoms. Therefore, Option A is correct. The other options are not supported by the text of Amuktamalyada or NCERT.

The military systems of Vijayanagara and its rivals relied heavily on cavalry. Since high-quality war horses could not be bred in sufficient numbers locally, horses were imported from Arabia and Central Asia. An effective cavalry force was essential for battlefield mobility, military expansion, and defense. This made horse imports strategically important. Therefore, Option D is correct.

The Portuguese became significant political actors because of their naval strength, military expertise, and access to firearms such as muskets. Their technological advantage made them valuable allies and trading partners. This influence extended into regional politics and warfare. Therefore, Option C is correct.

Krishnadeva Raya captured the Raichur doab and strengthened Vijayanagara's position against neighboring powers. This achievement demonstrated his military capability and strategic leadership. The conquest became one of the major successes of his reign. Therefore, Option C is correct.

NCERT emphasizes that relations between Vijayanagara rulers and Deccan Sultans were not always hostile. Political alliances, diplomatic interventions, and mutual support occurred when beneficial. The intervention of the Sultan of Bijapur in succession disputes demonstrates this pragmatic political relationship. Therefore, Option A is correct.

After Krishnadeva Raya's death, the empire faced growing internal challenges. Powerful military chiefs known as nayakas increasingly asserted independence and challenged central authority. These rebellions weakened imperial unity and contributed to political instability. Therefore, Option D is correct.

Many nayakas gradually transformed their territories into independent kingdoms. This process reduced the authority of the central government and accelerated the fragmentation of the Vijayanagara Empire. Thus, Option B correctly explains how the imperial structure weakened.

Rama Raya frequently attempted to manipulate rivalries among the Deccan Sultanates. Eventually, the Sultanates recognized the threat and united against Vijayanagara. This alliance defeated Rama Raya at the Battle of Rakshasi-Tangadi (Talikota) in 1565. Therefore, Option A is correct.

Rama Raya was the chief political and military leader of Vijayanagara during its later phase. He personally led the forces at the Battle of Rakshasi-Tangadi against the combined Deccan Sultanates. The defeat proved disastrous for the empire. Hence, Option D is correct.

After the sack of Vijayanagara, the Aravidu rulers relocated their administrative centres. They ruled successively from Penukonda and Chandragiri, allowing the dynasty to continue despite the destruction of the original capital. Therefore, Option B is correct.

Following the Battle of Rakshasi-Tangadi in 1565, Vijayanagara was plundered and devastated by the victorious Sultanate armies. The city was eventually abandoned, forcing the Aravidu rulers to establish new centres of administration in eastern regions. Thus, Option C is correct.
