Who amongst the following was shocked by Chauri-Chaura incident which…

The correct answer is Option (1) → Mohandas Karamchand Gandhi

At Chauri Chaura, a village in the Gorakhpur district of present Uttar Pradesh, an angry crowd of protesters set fire to the police station in February 1922, and 22 policemen were killed. Mahatma Gandhi, who had launched the Non-Cooperation Movement in 1920 on the condition that it stay non-violent, was deeply shocked and called the movement off; the Congress Working Committee approved the decision at Bardoli.

Note: It seems that there is a mistake in the original NTA paper, which says that the movement was withdrawn on 5 February 1922. The Chauri Chaura incident took place on 4 February 1922, and the movement was called off on 12 February 1922, when the Congress Working Committee met at Bardoli. The date does not change the answer.
