Why did khadi become important in the Non-Cooperation Movement?

Correct answer: It became a symbol of swadeshi and self-reliance

Khadi became important because it represented swadeshi, self-reliance, and resistance to dependence on imported British cloth. Spinning and wearing khadi connected ordinary people with Indian production and gave the national movement a visible everyday symbol. Thus option A is correct. Khadi was not the identity of foreign mills, a uniform limited to government employees, or an instrument of military recruitment.
