Correct option is D
Mahatma Gandhi delivered the Presidential address at the Cow Protection Conference held in December 1924. This conference took place at a time when communal tensions were high, and Gandhi used the platform to urge for communal harmony and non-violence. He emphasized that cow protection should not become a means of provoking violence against other religious communities, particularly Muslims, but rather be pursued through peaceful persuasion and moral influence. His speech was notable for trying to bridge religious divides and appeal to the conscience of the Hindu community to uphold the principle of ahimsa (non-violence) even in matters close to religious sentiments like cow protection.
