Which Hindu Rajya has been mentioned byBabar in his Babarnama :

Orissa
Gujarat
Mewar
Kashmir

The correct answer is (c), Mewar.

Mewar was a Rajput kingdom located in present-day Rajasthan, India. It was one of the most powerful and influential Rajput kingdoms, and its rulers were known for their bravery and military prowess. Mewar was founded in the 7th century by Bappa Rawal, and it reached its zenith under the reign of Rana Pratap Singh (1540-1597). Rana Pratap was a fierce warrior who fought against the Mughal emperor Akbar, and he is considered to be one of the greatest Rajput heroes.

Babar, the founder of the Mughal Empire, invaded Mewar in 1527. He was defeated by Rana Sanga, the ruler of Mewar, at the Battle of Khanwa. However, Babar returned to Mewar in 1528 and defeated Rana Sanga at the Battle of Ghaggar. After this defeat, Mewar was forced to pay tribute to the Mughals.

Despite being under Mughal suzerainty, Mewar remained a powerful kingdom. It continued to resist Mughal expansion, and it played a key role in the Rajput rebellion against the Mughals in the 17th century. Mewar finally became independent from the Mughals in 1707, after the death of Aurangzeb.

The other options are incorrect because they are not Hindu kingdoms that were mentioned by Babar in his Babarnama. Orissa was a Hindu kingdom located in present-day Odisha, India. Gujarat was a Muslim kingdom located in present-day Gujarat, India. Kashmir was a Muslim kingdom located in present-day Jammu and Kashmir, India.
