Who among the following Mughal rulers built the Agra Fort?

Akbar

The correct answer is Option 4- Akbar

The Mughal emperor Akbar built the Agra Fort.

Akbar began construction on the Agra Fort in 1565 and completed it in 1573. The fort was built on the site of an earlier fort, which had been built by the Sikandar Lodi dynasty. Akbar rebuilt the fort using red sandstone, which he quarried from nearby Dholpur. The fort is a massive structure, with a perimeter of over 2.5 kilometers. It is also well-defended, with high walls, towers, and a moat.

The Agra Fort was used by the Mughals as a royal residence and a military base. It was also a center of government and administration. The fort is a UNESCO World Heritage Site and is one of the most popular tourist destinations in India.
