Solution:HSRA stands for Hindustan Socialist Republican Army.
Many nationalists believed that non-violent means could not prevail in the fight against the British. At a gathering in Delhi's Ferozeshah Kotla field in 1928, the Hindustan Socialist Republican Army was established. Bhagat Singh, Jatin Das, and Ajoy Ghosh were some of its leaders. The HSRA attacked several British power symbols in a series of dramatic events around India. In the Legislative Assembly in April 1929, Bhagat Singh and Batukeswar Dutta exploded a bomb. Bhagat Singh was 23 years old when the colonial authorities tried and executed him.
