Answer is Wrong!
Answer is Right!
The correct answer is B. only 2.
Mica is a mineral that is used in a variety of applications, including electrical insulation, cosmetics, and roofing. The best mica ore in the world is obtained from the Jharia coalfield in Jharkhand, India. The Jharia coalfield is the largest coalfield in India and is known for its high-quality mica ore. The mica ore from Jharia is used in a variety of products, including electrical insulation, cosmetics, and roofing.
The other options are incorrect because they do not represent the best mica ore in the world. Dhanbad, Hazaribagh, and Kalti are all coalfields in India, but they do not produce the best mica ore.
