The correct answer is option 4, Kerala. The first non-Congress government was set up in Kerala after India gained independence. This government was known as the E. M. S. Namboodiripad ministry and was formed in 1957. It marked a significant political shift as it was the first time that a non-Congress party came to power in a state in independent India. The Communist Party of India won the state assembly elections in Kerala and formed the government. This event is considered a landmark in Indian politics as it challenged the dominance of the Congress party and showed that other political parties could also govern effectively.
