Which among the following places was not a centre of the revolution of 1857?

This is the correct answer because Jaipur was not a major center of the Indian Rebellion of 1857. During the revolt, the ruler of Jaipur, Maharaja Ram Singh II, remained loyal to the British and supported the British East India Company. Unlike places such as Auwa and Neemuch, where open rebellion occurred, Jaipur did not witness any major uprising or military resistance against British rule. This loyalty helped Jaipur avoid becoming a revolutionary center during 1857.
