Correct option is B
Statement 1: Natural gas occurs in Gondwana beds – This statement is incorrect. Natural gas is typically found in sedimentary rocks, but it is not specifically associated with the Gondwana beds. The Gondwana rock system is primarily known for its rich coal deposits, particularly in India, in states like Jharkhand, Odisha, and Chhattisgarh.
Statement 2: Mica occurs in abundance in Kodarma – This statement is correct. The Kodarma region, located in Jharkhand, is one of the world's largest producers of mica, a mineral used extensively in electrical and cosmetic industries. Kodarma is often referred to as the "Mica capital of India" due to its rich mica reserves.
Statement 3: Dharwar rocks are famous for petroleum – This statement is incorrect. The Dharwar rock system, one of the oldest geological formations in India, is famous for iron ore, gold, and manganese, but not petroleum. Petroleum reserves are usually found in younger sedimentary rock formations, such as those in the Tertiary period.
