Assertion (A): Antibiotics inhibit the growth of disease-causing bacteria.
Reason (R): Antibiotics are obtained from different moulds.

Options

A. Both A and R are true and R is the correct explanation for A.
B. Both A and R are true, but R is not the correct explanation for A.
C. A is true and R is false.
D. A is false and R is true.

Explanation

To analyze the assertion and reason provided in the question, we can break it down step by step:

### Step 1: Understand the Assertion (A)
The assertion states that "Antibiotics inhibit the growth of disease-causing bacteria."
- **Explanation**: Antibiotics are substances that specifically target bacteria and prevent their growth or kill them. They are crucial in treating bacterial infections.

### Step 2: Understand the Reason (R)
The reason states that "Antibiotics are obtained from different moulds."
- **Explanation**: Many antibiotics are derived from natural sources, including moulds (fungi). For example, penicillin, one of the first antibiotics discovered, comes from the Penicillium mould.

### Step 3: Evaluate the Truth of Assertion and Reason
- **Assertion (A)**: True. Antibiotics do inhibit the growth of disease-causing bacteria.
- **Reason (R)**: True. Antibiotics are indeed obtained from different moulds.

### Step 4: Determine the Relationship Between Assertion and Reason
- While both the assertion and the reason are true, the reason does not explain why antibiotics inhibit the growth of bacteria. The assertion describes the function of antibiotics, while the reason describes their source.

### Conclusion
- Both the assertion and the reason are true, but the reason does not justify the assertion. Therefore, the correct answer would be that both statements are true, but the reason is not the correct explanation for the assertion.

### Final Answer
Both Assertion (A) and Reason (R) are true, but Reason (R) does not explain Assertion (A).
