The Chauhan ruler Arnoraja built which important lake in Ajmer?

Explanation

Ana Sagar Lake is a scenic artificial lake commissioned and built by Arnoraj Chauhan, son of Ajaypal Chauhan, in Ajmer between 1135 and 1150 AD. Arnoraj was also known as Anaji, and the name Ana Sagar derives from his name. Its later Mughal association is separate: Jahangir laid out Daulat Bagh Gardens near the lake, and Shah Jahan added five pavilions, or baradaris, between the garden and the lake.

Why the other options are wrong

• (A) Pichola Lake is wrong because the question asks for Arnoraja's important lake in Ajmer, while Pichola Lake is in Udaipur.
• (C) Pushkar Lake is wrong because it is a natural lake, whereas Ana Sagar is the artificial lake built by Arnoraj Chauhan.
• (D) Fateh Sagar is wrong because it is in Udaipur, not Ajmer, and the relevant Chauhan-built lake is Ana Sagar.

Concept

This tests Rajasthan's medieval political history through built heritage associated with the Chauhans of Ajmer. Such questions recur in RAS because lakes, forts and temples often link rulers, places and chronology in one factual prompt.
