'हिंदूस्थान सोशालिस्ट रिपब्लीकन असोसिएशन' या संघटनेच्या स्थापनेत कोणाचा पुढाकार होता ?

The correct answer is Option D (Bhagat Singh).

Key Points:
• Formation of HSRA (1928):
• In September 1928, at a historic conclave of young revolutionaries held at Feroz Shah Kotla Ground in Delhi, the Hindustan Republican Association (HRA) was restructured as the Hindustan Socialist Republican Association (HSRA).
• Bhagat Singh took the primary ideological and organizational initiative to inject the goal of Socialism into the revolutionary movement and rename the organization accordingly.
• Together with Chandrashekhar Azad (Commander-in-Chief), Sukhdev, and Bhagwati Charan Vohra, Bhagat Singh steered the movement towards establishing an egalitarian socialist republic in India free from all forms of capitalist and imperialist exploitation.
• (Sachindranath Sanyal had founded the earlier HRA in 1924, but HSRA was the creation of Bhagat Singh and his comrades).
• Key Takeaway: Bhagat Singh took the initiative to transform HRA into the Hindustan Socialist Republican Association (HSRA) in 1928.
