The correct options are
A Donations to god were not mandatory
B Expensive yagnas were not mandatory
D Caste had no relevance
Before the Bhakti Movement, people had to perform expensive yagnas and donate to temples and Brahmins to please the gods. Certain sections of society were earlier denied permission to worship gods because of the notions of purity that came with caste. The Bhakti Movement began propagating the idea that only devotion to god was mandatory, nothing else. Donations and expensive yagnas were not mandatory and caste had no relevance.
