Answer
The answer is Congress. Periyar, also known as E. V. Ramasamy Naicker, was a social reformer and activist in India. He was a prominent leader of the Dravidian movement and the Self-Respect Movement. Periyar rejected the influence of the Indian National Congress, which was dominated by upper-caste Hindus. He believed that the Congress did not represent the interests of the lower castes, and he advocated for a separate Dravidian state.
