Assertion: Velamen is hygroscopic in nature and absorbs environmental moisture.
Reason: Velamen is common in orchids which are epiphytes.

Options

A. (a) If both Assertion and Reason are true and the Reason is the correct explanatin of the Assertion.
B. (b) both Assertion and Reason are true, but the Reason is not the correct explanation of the Assertion.
C. (c) If Assertion is true, Reason is false.
D. (d) If both Assertion and Reason are true.

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that "Velamen is hygroscopic in nature and absorbs environmental moisture." This means that velamen, a specific type of tissue found in certain plants, has the ability to attract and retain moisture from the environment.

2. **Evaluating the Reason**: The reason provided is that "Velamen is common in orchids which are epiphytes." This indicates that velamen is typically found in orchids, which are a type of plant that grows on other plants (epiphytes) and often absorbs moisture and nutrients from the air and rain.

3. **Analyzing the Relationship**: While both statements are true, the reason does not directly explain why velamen is hygroscopic. The assertion focuses on the hygroscopic nature of velamen, while the reason simply states that it is found in orchids, without explaining the significance of this characteristic.

4. **Conclusion**: Since both the assertion and reason are true, but the reason does not correctly explain the assertion, the appropriate answer is that both statements are true but the reason is not the correct explanation for the assertion.

5. **Final Answer**: The correct option is B: Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
