Arrange the following events in a chronological order and select the correct answer from the codes given below: I. Appointment of Simon Commission II. JallianwalaBagh Massacre III. Mahatma Gandhi’s Dandi March IV. Death of Ferozshah Mehta

The correct answer is A, the sequence IV, II, I, III. Anchor each event to its date and the order follows.

• IV, Death of Ferozshah Mehta (5 November 1915): the Bombay Congress stalwart died in 1915, the earliest of the four.
• II, Jallianwala Bagh Massacre (13 April 1919): at Amritsar, in the aftermath of the Rowlatt Act agitation.
• I, Appointment of the Simon Commission (November 1927): the all-white statutory commission under Sir John Simon was constituted in 1927 to review the Government of India Act 1919. It reached India only in February 1928.
• III, Dandi March (12 March to 6 April 1930): Gandhi's Salt Satyagraha, launched from Sabarmati.

Core concept: the 1919 to 1930 stretch is the Gandhian mass-mobilisation phase. The Simon Commission boycott led to the Nehru Report and the Purna Swaraj demand at Lahore in 1929, which set up the Dandi March. For Mains, this sequence shows how a constitutional exercise imposed without Indian representation pushed the movement towards civil disobedience.

Trap: aspirants place the Simon Commission before Jallianwala Bagh because they remember the boycott, or they assume Ferozshah Mehta died after 1919.
