Which one of the following events, was characterised by Montague as ‘Preventive Murder'?

1. The question asks which event was described by Edwin Montagu (Secretary of State for India) as 'Preventive Murder'. 2. This phrase was used by Montagu in the context of the Hunter Committee Inquiry into the Massacre of Jallianwala Bagh (Amritsar Massacre) of April 1919. 3. While Montagu condemned the event, the term specifically reflected the justification offered by General Dyer (that the firing was 'preventive' to curb potential rebellion), which Montagu implicitly criticized through this characterization. 4. The other events listed occurred at different times and were not described by Montagu in this specific manner.
