The correct option is D Rajah of Travancore - Patron of Vaikuntar
Vaikunda Swamigal founded Samathuva Samajam to unite people of various castes by organising inter-dining. Calling himself Vaikundar, he requested the people to give up all the irrelevant rites and rituals in their worship. He protested against the British and the rule of Rajah of Travancore, and termed them White devils and Black devils respectively. He was imprisoned by the Maharajah of Travancore, but he never gave up his principles. His followers called him Ayya, meaning father. His ideas are collected into a text called Akila Thirattu and his cult was known as Ayya Vazhi.
