The correct option is C.
Mahatma Gandhi’s first use of a hunger strike (fasting unto death) as a public protest method to achieve a specific desired goal occurred during the Ahmedabad Mill Strike in 1918. He undertook the fast to support the mill workers’ demand for a wage increase and to pressure the mill owners to agree to arbitration. While Gandhi experimented with fasting for self-purification earlier, including in South Africa, the Ahmedabad fast is widely recognized as his first instance of using it as a political weapon in India.
In South Africa, Gandhi developed his philosophy of Satyagraha (truth force), employing methods like non-violent resistance and civil disobedience (e.g., against the Black Act in 1906). Champaran (1917) was his first Satyagraha movement in India, focusing on the indigo cultivators’ issues, but did not involve Gandhi’s personal hunger strike as a primary tactic at that time.
