The correct answer is option 2, Aurobindo Ghosh. The Doctrine of Passive Resistance is a strategy used in nonviolent resistance, where individuals or groups choose to peacefully resist an oppressive or unjust system. Aurobindo Ghosh, also known as Sri Aurobindo, was an Indian philosopher, poet, and nationalist leader who played a significant role in India`s struggle for independence from British rule. He advocated for the use of spiritual and philosophical principles in the fight for freedom, including the concept of passive resistance. Ghosh believed that nonviolent resistance could bring about social and political change without resorting to violence. Therefore, he is considered the first propounder of the Doctrine of Passive Resistance. The other options, B.G. Tilak, Lajpat Rai, and G. K. Gokhale, were also important figures in India`s freedom movement, but they did not specifically propagate the Doctrine of Passive Resistance.
