Babur laid the foundations of mughal empire by defeating which of the following ruler?

Ibrahim Lodi

The correct answer is Option 1- Ibrahim Lodi

Babur laid the foundations of the Mughal Empire by defeating Ibrahim Lodi at the First Battle of Panipat in 1526.

Ibrahim Lodi was the last Sultan of the Lodi dynasty, which had ruled over India for over 100 years. Babur was a descendant of Timur and Genghis Khan, and he had come to India in search of a new kingdom to conquer.

The First Battle of Panipat was a decisive victory for Babur. He used his superior military tactics and artillery to defeat Ibrahim Lodi's much larger army. Babur's victory at Panipat marked the beginning of the Mughal Empire in India.

The other options you mentioned are incorrect:

• Daulat Khan Lodi was a governor under the Lodi dynasty. He had invited Babur to invade India, but he later betrayed him.
• Krishnadeva Raya was the ruler of the Vijayanagara Empire in South India. He was a powerful ruler, but he was never defeated by Babur.
• Sher Shah Suri was a Pashtun warlord who defeated Babur's son, Humayun, at the Battle of Chausa in 1539. He founded the Suri dynasty, which ruled over India for a brief period before being overthrown by the Mughals in 1555.
