Name of the revolutionary who hurled bomb on Lord Hardinge was Correct Answer Ras Bihari Bose

It is said that the Delhi Conspiracy(also known as Delhi Lahore Conspiracy Case or Hardinge Bomb Case) was hatched by Ras Bihari Bose, but was never proved.

• On 23 December 1912, a Bomb was thrown at the Viceroy Lord Hardinge when his procession was moving from Chandni Chowk.
• The Viceroy was wounded in the attempt, but his Mahavat (driver and keeper of an elephant) was killed.
• The government strengthens its efforts to destroy the underground activities. 
• Ras Bihari Bose went underground and successfully fled to Japan, where he lived till he died a few years before the conclusion of the Second World War.
• Before fleeing to Japan, he was involved in the Ghadar Conspiracy.
• In the trial of this Delhi Conspiracy Case, Basant Kumar Biswas Amir Chand and Avadh Behari were convicted and executed.

Thus, it is right to say that Ras Bihari Bose hurled a bomb on Lord Hardinge.
