Who threw two bombs on the Door of the Central Assembly in New Delhi on April 8, 1929?

Answer: Option D

Bhagat Singh also disapproved that the two should be escorted after the bombing by the rest of the party. On 8 April 1929, Singh and Dutt threw a bomb onto the corridors of the assembly and shouted “Inquilab Zindabad!” (“Long Live the Revolution!”). This was followed by a shower of leaflets stating that it takes a loud voice to make the deaf hear.
