Assertion`:-` Cells of epithelium tissues rest on a thin basement membrane.
Reason`:-` Basement membrane has both fibrous and basal lamina secreted by connective tissue and epithelial tissue respectively.`-`

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 Assertiion.
C. If Assertion is True but the Reason is False.
D. If both Assertion & Reason are False

Explanation

**Step-by-Step Solution:**

1. **Understanding the Assertion:**
- The assertion states that "Cells of epithelium tissues rest on a thin basement membrane."
- This is true because epithelial cells are anchored to the underlying connective tissue by the basement membrane, which provides structural support.

2. **Understanding the Reason:**
- The reason states that "Basement membrane has both fibrous and basal lamina secreted by connective tissue and epithelial tissue respectively."
- This is also true. The basement membrane is composed of two layers: the basal lamina (secreted by epithelial cells) and the reticular lamina (secreted by connective tissue).

3. **Connecting Assertion and Reason:**
- The assertion and reason are related. The basement membrane provides a foundation for epithelial cells, and its composition (fibrous and basal lamina) is crucial for its function.
- Therefore, the reason correctly explains why the assertion is true.

4. **Conclusion:**
- Both the assertion and reason are true, and the reason is the correct explanation for the assertion. Thus, the answer is that both statements are true and the reason is the correct explanation for the assertion.

**Final Answer:**
Both the assertion and reason are true, and the reason is the correct explanation for the assertion.
