The country in South Asia that is the world’s biggest supplier of mica is c. India.

India has been a dominant player in the global mica market, accounting for a significant portion of the world’s mica production. Mica is chiefly mined in the states of Jharkhand and Bihar in India, and it is widely used in various industries, including cosmetics, electronics, and construction.

While other countries in the region, like Bhutan and Bangladesh, do produce mica, none match India's scale of supply. However, mica mining in India has raised concerns regarding labor practices and environmental impact, leading to increased scrutiny on sourcing practices in industries that utilize mica.
