Assertion : None autotrophic bacteria carry out chemosynthesis.
Reason : Chemosynthesis bacteria trap the small amount of energy released from inorganic compound's oxidation to use in the reaction that synthesize carbohydrates.

Options

A. If both the assertion and the reason are true and the reason is a correct explanation of the assertion
B. If both the assertion and reason are true but the reason is not a correct explanation of the assertion
C. If the assertion is true but the reason is false
D. If both the assertion and reason are false

Answer

B

Explanation

Chemosynthetic autotroph are non photosynthetic autotroph i.e. photosynthetic pigments are present. They use chemical energy instead of light energy for food synthesis. Chemical energy is obtained from oxidation of organic / inorganic compound.
