Sedimentary rocks formed from the remains of once-living things are
a. metamorphic
c. organic
b. detrital
d. none of the above

The correct answer is - c. organic.

Sedimentary rocks, unlike the others, can be composed of both organic and non organic matter. Since they are formed on the surface and are the softest of the rocks, when an animal or plant dies their remains can be naturally cemented with the rock itself if the conditions are right. The best known member of this group of rocks is the coal which is formed by dead remains of plants but passing through multiple processes it also accumulated lots of carbon as well and is used as a fuel. Other members of this group include bioclastic and skeletal limestone, and coquina.
