Answer:
Correct Answer: D
Solution:
Chemosynthetic bacteria may or may not have photosynthetic pigments.
For the synthesis of their own organic food, (carbohydrates), they obtain carbon from $ CO_2 $ of the atmosphere, necessary energy from oxidation of inorganic or organic compounds, such as hydrogen sulphide $ (H_2S), $ ferrous compounds $ (Fe^{2+}}), $ molecular hydrogen $ (H_2) $ ammonia $ (NH_3) $ and nitrites $ (NO_2^-).$
