Who was the leader of the anti-caste movement and the founder of In dependent Labour Party?

The correct answer is Babasaheb Bhimrao Ambedkar.

Here is a step-by-step explanation of why this option is correct:

1. Leader of the Anti-Caste Movement:
Babasaheb Bhimrao Ambedkar (Dr. B.R. Ambedkar) was a pioneering social reformer and jurist who dedicated his life to fighting social discrimination against the untouchables (Dalits) in India. He was a champion of human rights and campaigned relentlessly against the inequities of the Hindu caste system.

2. Founder of the Independent Labour Party (ILP):
To represent the interests of the working class and marginalized communities, Dr. Ambedkar founded the Independent Labour Party (ILP) in August 1936. The party opposed the caste system and fought for the rights of industrial workers, agricultural laborers, and tenants, aiming to integrate social reform with economic justice.

3. Incorrect Options:
- Acharya Narendra Dev was a leading theorist of the Congress Socialist Party and a prominent figure in the Indian socialist movement.
- Rafi Ahmed Kidwai was an independence activist and a prominent socialist politician from Uttar Pradesh who served as a minister in the central cabinet.
- A.K. Gopalan was a prominent Marxist philosopher and leader of the Communist Party of India (Marxist).

Therefore, Babasaheb Bhimrao Ambedkar is the leader who matches both descriptions as the leader of the anti-caste movement and the founder of the Independent Labour Party.
