Correct answer is (c) Humus
 
Easiest explanation: The dark amorphous organic matter rich in cellulose and lignin that is highly resistant to any microbial action and decomposes at a slower rate is called humus. It is formed due to the decomposition of the organic remains such as dead plants remains dead animal remains and fecal matter.
