The correct answer is (c) Kerala.
Kerala is a state in India that is known for its high literacy rate, low population growth rate, and high standard of living. It is also one of the most politically stable states in India. The Communist Party of India (Marxist) (CPI(M)) has been the ruling party in Kerala since 1957, making it the longest-serving democratically elected communist government in the world.
The CPI(M) was founded in 1964 as a split from the Communist Party of India (CPI). The CPI(M) is a Marxist-Leninist party that advocates for a socialist revolution in India. The party has a strong base of support in Kerala, where it has implemented a number of progressive policies, including land reforms, education reforms, and health reforms.
The CPI(M)’s rule in Kerala has been marked by a number of achievements, including a high standard of living, a low crime rate, and a high literacy rate. However, the party has also been criticized for its authoritarian style of governance and its suppression of dissent.
Despite these criticisms, the CPI(M) remains the most popular political party in Kerala. The party is expected to continue to rule the state for the foreseeable future.
The other options are incorrect because they are not states in India.
