Assertion (A): Metals are sonorous.
Reason (R): They are generally brittle in the solid state, they break into pieces when hammered.

Options

A. Both A and R are true and R is the correct explanation of A.
B. Both A and R are true but R is NOT the correct explanation of A
C. A is true but R is false
D. A is false and R is true.

Explanation

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

### Step-by-Step Solution:

1. **Understanding the Assertion (A)**:
- The assertion states that "Metals are sonorous."
- Sonorous means that a material can produce a ringing sound when struck. Metals, such as copper and aluminum, are known for their ability to produce sound, which is why they are often used in musical instruments and bells.

2. **Understanding the Reason (R)**:
- The reason states that "They are generally brittle in the solid state, they break into pieces when hammered."
- Brittleness refers to the tendency of a material to break or shatter when subjected to stress, such as hammering. However, this is not true for most metals. Metals are typically malleable and ductile, meaning they can be hammered into thin sheets or drawn into wires without breaking.

3. **Evaluating the Truth of Assertion (A)**:
- Since metals can produce sound when struck, the assertion is true.

4. **Evaluating the Truth of Reason (R)**:
- The reason provided is incorrect because metals are not generally brittle; they are malleable and ductile. Therefore, the reason is false.

5. **Conclusion**:
- Since the assertion is true and the reason is false, we conclude that the correct relationship is that Assertion (A) is true, and Reason (R) is false.

### Final Answer:
- Assertion (A) is true, and Reason (R) is false.
