The correct answer is A. Humayun.
Humayun’s Tomb is a Mughal mausoleum located in Delhi, India. It was commissioned by Bega Begum, Humayun’s wife, in 1562, and completed in 1572. The tomb is considered to be one of the finest examples of Mughal architecture, and is a UNESCO World Heritage Site.
Bega Begum was the first wife of Humayun, and the mother of Akbar. She was a powerful and influential figure in the Mughal court, and played a major role in the construction of Humayun’s Tomb.
Babur was the founder of the Mughal Empire, and the father of Humayun. He was a great conqueror, and his empire stretched from Afghanistan to Bengal.
Akbar was the third Mughal emperor, and the grandson of Humayun. He was a great ruler, and his empire reached its peak under his reign.
The other options are incorrect because they are not the people who built Humayun’s Tomb.
