Consider the following events: 1. Launch of Non-Cooperation Movement 2. All-India Khilafat Conference in Delhi 3. Passing of the Rowlatt Act 4. Jallianwala Bagh incident Which one of the following is the correct chronological order of the given events (earliest to latest)?

The Rowlatt Act was passed in March 1919, making it the earliest of the four events. The Jallianwala Bagh massacre took place on 13 April 1919, shortly after. The All-India Khilafat Conference was held in Delhi in November 1919, where the strategy of non-cooperation was first discussed. The Non-Cooperation Movement was formally launched by Mahatma Gandhi in August 1920. Therefore the correct chronological order from earliest to latest is 3 (Rowlatt Act) → 4 (Jallianwala Bagh) → 2 (Khilafat Conference, Delhi) → 1 (Non-Cooperation Movement).
