Jaimal of Merta and Patta of Kelwa are remembered for the defence of which fort against Akbar?

The correct answer is B, Chittorgarh. Akbar laid siege to Chittorgarh in 1567 and took it in February 1568. Maharana Udai Singh II had withdrawn to the hills, leaving the fort to Jaimal of Merta and Patta of Kelwa, who died fighting; Akbar was impressed enough to set up their statues at the Agra fort gate. This was the third great sack of Chittorgarh, after those of Alauddin Khalji and Bahadur Shah of Gujarat.

Option A is wrong because Ranthambore fell to Akbar in 1569, the year after Chittorgarh, and its defender was Rao Surjan Hada of Bundi, not Jaimal and Patta. Option C is wrong because Mehrangarh at Jodhpur was never stormed in this way. Option D is wrong because Junagarh at Bikaner was built by Rai Singh in 1589, more than twenty years after the siege in question.
