e) a, b and c. Gandhi made fasting a major instrument for Satyagraha, or non-violent resistance, in British India, and he used it as a means of protesting various causes.
Gandhi undertook a fast in 1922 in support of the Ahmedabad Mill Workers strike, which was a labor dispute that arose over the treatment of workers in the textile industry in Ahmedabad, India.
Gandhi also undertook a fast in 1932 in protest of the Communal Award, which was a policy that granted separate electorates to untouchables, or those who were considered to be of a lower social status in India. Gandhi believed that this policy would further divide the people of India along communal lines and would undermine the principles of unity and equality that he advocated.
In 1947, Gandhi also undertook a fast in support of communal harmony in India, as tensions between Hindus and Muslims were rising in the lead-up to the partition of India and the creation of the independent states of India and Pakistan.
Finally, Gandhi also undertook a fast in 1928 in support of the Bardoli Satyagraha, which was a non-violent resistance campaign that was organized in protest of a tax hike in the Bardoli region of Gujarat, India.
Therefore, the correct answer is (e) a, b and c.
