The question asks to identify the Indian revolutionary who assassinated Michael O'Dwyer. Michael O'Dwyer was the Lieutenant Governor of Punjab during the British Raj and is infamous for his role in sanctioning the Jallianwala Bagh massacre in Amritsar in 1919.
Bhagat Singh, Sukhdev Thapar, and Rajguru were prominent revolutionaries involved in other significant actions against British rule, notably the killing of John P. Saunders, but they did not assassinate Michael O'Dwyer.
