The correct option is D Vallabhbhai Patel
The Bardoli Satyagraha was a peasants’ movement against the British government’s decision to raise land revenue. It was led by Vallabhbhai Patel, and its success gave rise to Patel becoming one of the main leaders of the independence movement. In this struggle, Vallabhbhai Patel got the title of “Sardar” by local farmers of Bardoli.
