Assertion: Cartilage and bone are rigid connective tissues.
Reason: Blood is a connective tissue.

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are True but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are false.

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that "Cartilage and bone are rigid connective tissues."
- **Explanation**: This is true because both cartilage and bone provide structural support and are classified as connective tissues. They have a rigid structure due to the specific composition of their extracellular matrix.

2. **Understanding the Reason**: The reason states that "Blood is a connective tissue."
- **Explanation**: This is also true. Blood is classified as a connective tissue because it consists of cells (red blood cells, white blood cells, and platelets) suspended in a liquid matrix called plasma.

3. **Evaluating the Relationship**: Now we need to determine if the reason provided is a correct explanation of the assertion.
- **Explanation**: While both statements are true, the reason does not explain the assertion. The assertion is about cartilage and bone, while the reason discusses blood, which is a different type of connective tissue.

4. **Conclusion**: Since both the assertion and reason are true, but the reason does not explain the assertion, the correct answer is that both assertion and reason are true, but the reason is not a correct explanation of the assertion.

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