Read the source given below and answer the question that follows:

Iron ore and mangoes are two important ferrous minerals mined in India. The two main ores of iron are magnetite and hematite. Magnetite has up to 70% iron, while hematite has 50-60% iron. Karnataka and Orissa are the main iron ore-producing states in India, followed by Chhattisgarh, Goa and Jharkhand. Major iron ore producing belts of India are the Orissa Jharkhand belt, the Durg-Bastar-Chandrapur belt, and the Bellary-Chitradurga-Chikmagalur-Tumkur belt and the Maharashtra-Goa belt.

High-grade hematite is mined in the Badampahar mines in Mayurbhanj and Kendujhar districts of Orissa. The Durg-Bastar-Chandrapur belt is spread over parts of Chhattisgarh and Maharashtra. These hills contain 14 deposits of hematite.

The Bellary-Chitradurga-Chikmagalur-Tumkur belt lies in Karnataka. The Kudermukh mines in this region hold one of the largest deposits of iron ore in the world. Orissa is the main manganese-producing state in India, followed by Madhya Pradesh and Karnataka.

The Maharashtra-Goa belt is spread over parts of Goa and the Ratnagiri district of Maharashtra. Steel is a mixture of several minerals besides iron ore, and one such important mineral is manganese. The reserves of non-ferrous minerals in India are not as abundant as those of ferrous minerals. Copper and bauxite are two important non-ferrous minerals mined in India. Copper is widely used in the electrical, electronic and chemical industries.

Answer the following MCQ by choosing the most appropriate option:

Which of the mines in India holds one of the largest deposits of Iron?
