B

Explanation:

The debris of marine organisms such as corals, shells, and algae accumulate in the bottom of marine waters and accumulate with sediments. This debris is made up of calcium carbonate and over time the pressure and temperatures after sedimentation layers result to formation of limestone that transforms the calcium carbonate to the form of calcite.
