The correct answer is c) Kasaragod.
Bauxite is a primary ore of aluminum. It is a hard, rock-like material that is found in the Earth’s crust. Bauxite is typically red, brown, or yellow in color. It is composed of aluminum oxide, iron oxide, and silica.
Bauxite is mined in open-pit or underground mines. The ore is then crushed and ground into a fine powder. The powder is then mixed with water and chemicals to extract the aluminum oxide. The aluminum oxide is then refined into aluminum metal.
India is one of the world’s largest producers of bauxite. The country’s bauxite reserves are estimated to be 5.5 billion tonnes. The major bauxite-producing states in India are Odisha, Jharkhand, Chhattisgarh, and Andhra Pradesh.
Kasaragod district in Kerala is also a potential source of bauxite. The district has an estimated bauxite reserve of 100 million tonnes. However, the mining of bauxite in Kasaragod has been opposed by environmental activists.
The other options are incorrect because they are not major bauxite-producing states in India. Ernakulam and Kollam are districts in Kerala, while Kannur is a district in Karnataka.
