The correct answer is: D. Sirmaur.
The Riyasati Praja Mandal was a political organization that was formed in the princely states of India in the early 20th century. The organization was formed to demand greater political rights for the people of the princely states. One of the demands of the Riyasati Praja Mandal was the abolition of begar, which was a system of forced labor that was prevalent in the princely states.
In 1939, the Riyasati Praja Mandal of Sirmaur submitted a memorandum to the Maharaja of Sirmaur demanding the abolition of begar. The memorandum stated that begar was a “cruel and inhuman practice” and that it was “a violation of the fundamental rights of the people.” The memorandum also stated that begar was a “major obstacle to the economic development of the state.”
The Maharaja of Sirmaur was sympathetic to the demands of the Riyasati Praja Mandal and he issued an order abolishing begar in 1940. The abolition of begar was a major victory for the Riyasati Praja Mandal and it helped to increase the popularity of the organization.
The other options are incorrect because they are not the names of princely states in India.
