The correct option is D Alauddin Khalji
On 26th August 1303, Alauddin Khilji of the Khilji Dynasty attacked and captured Chittorgarh by defeating Ratan Singh in a historic battle. This was an unequal battle since Khilji’s army was much bigger than Ratan Singh’s army. After winning Khilji handed over the Chittorgarh to his son Khizr Khan.
