The correct option is A Humayun's Tomb, Delhi
Humayun's Tomb built in 1570, is of particular cultural significance as it was the first garden-tomb on the Indian subcontinent. The tomb was commissioned by Bega Begum, Humayun’s Persian wife and chief consort in 1565 AD. It was completed in 1572 AD under the patronage of the Mughal Emperor Akbar. It is one of the best preserved Mughal monuments and was declared a UNESCO World Heritage site in 1993.
