Correct Option: A

Endogenous chemical agents are those that originate from within the organism, tissue or cell. Endogenous chemical agents and genetic mutations are collectively called intrinsic or internal factors affecting human health. The diseases caused by intrinsic factors are called organic or metabolic diseases. Chemicals which may be endogenous are urea, uric acid, hormones and enzymes.
