[A] : No any autotrophic bacteria carry out chemosynthesis .
[R] : Chemosynthetic bacteria take energy from sun for the synthesis of food .

Options

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

Explanation

To analyze the statements provided in the question, we need to evaluate both the assertion [A] and the reason [R] regarding chemosynthetic bacteria.

### Step 1: Understand the Assertion [A]
The assertion states: "No autotrophic bacteria carry out chemosynthesis."

- **Explanation**: Autotrophic bacteria are organisms that can produce their own food. Chemosynthesis is a process where certain bacteria synthesize organic compounds using energy derived from chemical reactions, rather than from sunlight (as in photosynthesis).
