Members of which National Association were led by Chandrashekhar Azad and Bhagat Singh?

Hindustan Socialist Republican Association

The correct answer is Option 1- Hindustan Socialist Republican Association

The National Association led by Chandrashekhar Azad and Bhagat Singh was the Hindustan Socialist Republican Association (HSRA).

The HSRA was a revolutionary socialist organization founded in 1928 in Delhi, India. It was a successor to the Hindustan Republican Association (HRA), which had been founded in 1923. The HSRA's goal was to achieve an independent and socialist India through armed revolution.

Azad and Singh were two of the most prominent members of the HSRA. Azad was the leader of the organization, while Singh was one of its most active members. The HSRA carried out a number of high-profile attacks against the British government, including the assassination of Lahore Superintendent of Police James A. Scott in 1928 and the bombing of the Central Legislative Assembly in Delhi in 1929.

Azad and Singh were eventually captured and executed by the British government in 1931. Despite their short lives, they had a profound impact on the Indian independence movement. The HSRA's legacy continues to inspire revolutionaries and socialists in India today.
