Answer: Option D

Explanation:

Chemotrophs can be defined as the organism which has the ability to get energy by the oxidation of electron donors present in the nearby environments.

These molecules in the environment can be organic or inorganic.These bacteria are usually called as thiobacillus denitrificans.

These bacteria reduce the nitrate into nitrite and the energy source for these bacteria is thiosulfate(sulfur).
