The correct answer is Option 2- Dadabhai Naoroji

Dadabhai Naoroji was the first Indian to be selected to the British House of Commons on a Liberal Party ticket. He was elected in 1892 as the MP for Central Finsbury.

Chandra Shekhar Azad, Bhimrao Ramji Ambedkar, and Bhagat Singh were all important figures in the Indian independence movement, but they were not elected to the British House of Commons.

Dadabhai Naoroji was a prominent Indian nationalist leader and one of the founders of the Indian National Congress. He was a vocal critic of British rule in India and advocated for self-government.

Naoroji's election to the British House of Commons was a significant event in the Indian independence movement. It showed that Indians were capable of participating in British political institutions and that they were demanding a greater voice in their own government.

Naoroji served as the MP for Central Finsbury from 1892 to 1895. During his time in Parliament, he spoke out on a variety of issues, including the civil rights situation in India, the condition of Indians in South Africa, and the economic drain from India to Britain.
