Which of the following is a calcareous sedimentary rock found in large quantities in Odisha?

The correct answer is Option C: Both (A) and (B)

Let's break down why:

Sedimentary Rock: This means the rock is formed from the accumulation and cementation of sediments like minerals and organic particles.

Calcareous: This term indicates that the rock is primarily composed of calcium carbonate (CaCO3).

Dolomite: Dolomite is a sedimentary rock similar to limestone but contains magnesium. It's still considered a calcareous rock because it has a significant amount of calcium and carbonate.

Limestone: Limestone is a sedimentary rock composed mostly of calcium carbonate. It's the classic example of a calcareous rock.

Therefore, since both Dolomite and Limestone are calcareous sedimentary rocks found in Odisha, the answer is Both (A) and (B).
