Solution

Chemotrophs are the organisms that obtain energy by the oxidation of electron donor. These molecules can be organic(Chemoorganotrophs) or inorganic (chemolithotrophs). In contrast, phototrophs utilize solar energy. Chemotrophs utilises inorganic energy sources of which, hydrogen sulphide, elemental sulfur, ferrous ions, molecular hydrogen, and ammonia are prominent example. Most are bacteria or archaea that lives in the hostile environments seen around deep sea vent, hot springs, geysers , etc. So, the correct answer is option A.
