Correct answer: A. Rana Kumbha
Explanation: The direct answer is A, Rana Kumbha. Kumbhalgarh Fort is strongly associated with Rana Kumbha, the fifteenth-century ruler of Mewar. He developed and strengthened the fort as an important part of Mewar’s defensive system. Step by step: identify the monument as Kumbhalgarh; place it in Rajasthan and the Mewar region; connect its major construction and expansion with Rana Kumbha. Option A is correct because historical tradition and standard textbooks link the fort’s construction to him. Option B, Maharana Pratap, is associated with resistance against the Mughal Empire and with Mewar, but he did not build Kumbhalgarh. Option C, Rana Sanga, was another important Mewar ruler, but the fort is not chiefly identified with his construction work. Option D, Sawai Jai Singh, belonged to Jaipur and is associated with observatories and Jaipur’s development, not Kumbhalgarh. Memory cue: “Kumbhalgarh—Kumbha.”
