Explanation:

All the statements are correct. Vaikom Satyagraha in Travancore (modern-day Kerala) was a movement for temple entry of the depressed classes. It happened at Vaikom near the Shiva Temple, Kottayam district, Kerala during 1924-25. Vaikom was at that point a neighborhood of the princely state of Travancore.

Background :According to the prevalent class structure in Kerala similar to the rest of India, low-caste Hindus weren't allowed to enter the temples. In Kerala, they weren't allowed even to steer on the roads that led to the temples also. At a Congress Party Meeting in the Kakinada in 1923, a report citing the discrimination that the depressed castes’ people were facing in Kerala was presented by T K Madhavan. It was after this session that movements against untouchability got promoted. A committee was formed in Kerala, comprising people of various castes to fight untouchability. The Vaikom movement started on March 30, 1924. At Vaikom Mahadeva Temple, lower caste people (Avarnas) were denied entry by the board. On 1st October 1924, a team of upper caste called Savarnas moved forward during a procession and submitted a petition to the Regent Maharani Sethu Lakshmi Bai of Travancore with about 25000 signatures for allowing entry to the temple for everybody.
