Assertion (A): The Battle of Khanua was certainly more decisive and significant than the First Battle of Panipat. Reason (R): Rana Sanga, the Rajput hero, was certainly a more formidable adversary than Ibrahim Lodi.

The correct answer is D because the Assertion is false while the Reason is true. The First Battle of Panipat 1526 is considered more decisive and significant than the Battle of Khanua 1527. Panipat resulted in the death of Ibrahim Lodi, the collapse of the Delhi Sultanate, and the formal establishment of the Mughal Empire in India. While Khanua was important for consolidating Baburs power, it was the victory at Panipat that provided him the throne and a base in India. The Reason is true because Rana Sanga was a more formidable adversary than Ibrahim Lodi. Rana Sanga was a seasoned warrior who led a powerful confederacy of Rajput kings and commanded a much larger and more disciplined military force than the Sultan of Delhi. Baburs own memoirs indicate that he viewed the Rajputs under Sanga as a greater threat to his survival in India than the Lodi dynasty.
