(B) II, I, IV, III
Jallianwala Bagh Massacre (April 1919) → Khilafat Committee, Bombay (March 1919 — but movement gained momentum post-massacre) → Withdrawal of NCM (1922) → Bardoli Satyagraha (1928).
The correct answer is (B) II, I, IV, III.
From the chapter: Khilafat Committee was formed in March 1919; Jallianwala Bagh was 13 April 1919; NCM was withdrawn in 1922 (after Chauri Chaura); Bardoli Satyagraha was 1928. So the order is II → I → IV → III. Examiners expect you to recall these dates precisely for chronological-order MCQs.
