Answer:

C

Step-by-step explanation:

Limestone, otherwise known as Calcium Carbonate, is an ocean sedimentary rock formed from the shells of dead organisms.

When these animals die, their shell and skeletal debris accumulate as a sediment that might be lithified into limestone. Limestones formed from this type of sediment are biological sedimentary rocks.
