Assertion: Sclereids are found in fuit walls of nuts, pulp of fruits like guave, pear and sapota andseed coats of legumes.
Reason: Sclereids are spherical, oval or cylinderical, highly thickeneddeadcells with narrow lumen.

Options

A. If both assertion and reason are true and reason is the correct explanantion of assertion
B. if both assertion and reason are true but reason is not the correct explanation of assertion.
C. if assertion is true but reason is false.
D. if both assertion and reason are false.

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that sclereids are found in the fruit walls of nuts, the pulp of fruits like guava, pear, and sapota, as well as in the seed coats of legumes.

2. **Identifying Sclereids**: Sclereids are a type of cell found in plants, specifically within a tissue called sclerenchyma. These cells are known for their rigidity and are typically dead at maturity.

3. **Examples of Sclereids**: The assertion provides specific examples where sclereids can be found:
- In the fruit walls of nuts, which provide protection and structural support.
- In the pulp of fruits like guava, pear, and sapota, where they contribute to the texture.
- In the seed coats of legumes, where they help protect the seeds.

4. **Understanding the Reason**: The reason states that sclereids are spherical, oval, or cylindrical, highly thickened dead cells with a narrow lumen. This description accurately reflects the characteristics of sclereids.

5. **Evaluating the Truth of Assertion and Reason**: Both the assertion and the reason are true statements. Sclereids are indeed found in the specified locations, and their structural characteristics are as described.

6. **Determining the Relationship**: While both statements are true, the reason does not directly explain the assertion. The assertion discusses where sclereids are found, while the reason describes their structure.

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

### Final Answer:
**Option 2**: Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
