Assertion: Quality of sound produced by an open pipe is better than a close pipe.
Reason : Open pipe produces all harmonies but a closed pipe does not.

Options

A. Statement-1 is True, Statement-2 is True and Statement-2 is a correct explanation for Statement-1
B. Statement-1 is True, Statement-2 is True and Statement-2 is NOT a correct explanation for Statement-1
C. Statement-1 is True, Statement-2 is False
D. Statement-1 is False, Statement-2 is True

Explanation

To solve the question, we need to analyze both the assertion and the reason provided.

### Step 1: Understand the Assertion
The assertion states that the quality of sound produced by an open pipe is better than that produced by a closed pipe.

- **Open Pipe**: An open pipe can vibrate in such a way that it produces a fundamental frequency and all harmonics (overtones). This means it can produce a richer and more complex sound.
- **Closed Pipe**: A closed pipe, on the other hand, can only produce the fundamental frequency and odd harmonics (1st, 3rd, 5th, etc.). This results in a sound that is less rich in harmonics compared to an open pipe.

### Step 2: Understand the Reason
The reason given states that an open pipe produces all harmonics, while a closed pipe does not.

- This statement is accurate because:
- An open pipe supports standing waves that can accommodate all harmonics.
- A closed pipe can only support standing waves that correspond to odd harmonics due to the boundary condition of having one end closed.

### Step 3: Analyze the Relationship Between Assertion and Reason
Now we need to determine if the reason correctly explains the assertion.

- While both the assertion and reason are true, the reason does not provide a complete explanation for why the quality of sound from an open pipe is better. The quality of sound is not solely determined by the presence of all harmonics; it also involves how these harmonics combine and the overall timbre produced.

### Conclusion
- **Assertion**: True
- **Reason**: True
- The reason is not a correct explanation for the assertion.

Thus, the answer to the question is that both the assertion and reason are true, but the reason is not the correct explanation for the assertion.

### Final Answer
Both the assertion and reason are true, but the reason is not a correct explanation for the assertion.
