The correct answer is (b) Rajasthan.
Sariska Tiger Reserve is a tiger reserve in Rajasthan, India. It is located in the Alwar district of Rajasthan, about 100 kilometers from Jaipur. The reserve was established in 1955 and is spread over an area of 869 square kilometers. It is home to a variety of wildlife, including tigers, leopards, sloth bears, and wild boars.
The reserve was once home to a large population of tigers, but the population declined significantly in the 1990s due to poaching and habitat loss. In 2005, the reserve was declared a critical tiger habitat by the Government of India. Since then, the government has taken steps to improve the security of the reserve and to increase the tiger population. As a result, the tiger population has increased significantly in recent years.
