Correct Answer: (c) Prafulla Chaki
Solution:Khudiram Bose and Prafulla Chaki went to Muzaffarpur Bihar to assassinate Kingsford, Chief Calcutta Presidency Magistrate. Khudiram Bose and Prafulla Chaki watched the usual movements of Kingsford and prepared a plan to kill him. On the evening of April 30, 1908, the duo waited in front of the gate of European club for the carriage of Kingsford to come. When a vehicle came out of the gate, they threw bombs and blew up the carriage. Unfortunately, the vehicle was not carrying Kingsford and instead, two innocent British ladies—Mrs. and Miss Kennedy (the wife and daughter of barrister Pringle Kennedy) were killed. The revolutionary duo fled. Prafulla committed suicide and Khudiram was later arrested and hanged.
