Correct answer: D. Sardar
Explanation: The direct answer is D, Sardar. Vallabhbhai Patel led the Bardoli Satyagraha in 1928 against increased land revenue. The peasants resisted peacefully, and the movement succeeded. Because of his effective leadership, the women of Bardoli gave Patel the honourific title Sardar, meaning leader or chief. Option A, Netaji, is the title associated mainly with Subhas Chandra Bose. Option B, Lokmanya, is strongly associated with Bal Gangadhar Tilak. Option C, Punjab Kesari, is associated with Lala Lajpat Rai. Option D, Sardar, is correct because Bardoli’s people gave this title to Vallabhbhai Patel. Exam cue: connect Bardoli with Patel and the title Sardar, and later connect him with the integration of princely states.
