Option D

Explanation:

Organic sedimentary rocks are the types of sedimentary rocks generally formed in swamps or water logged areas over years where remains of living organisms like leaf or dead bodies of animals get petrified and stored under the soil for considerable amount of time and due to carbon deposition, it forms rocks. Most classical example of this type of sedimentary rocks is coal.
