The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "Transpiration occurs through stomata." - Transpiration is the process where water vapor is lost from the plant to the atmosphere, primarily occurring through small openings called stomata, which are mainly located on the leaves. - Therefore, this assertion is **True**. 2. **Understanding the Reason**: - The reason states that "Guttation is due to root pressure." - Guttation is the process where water droplets are exuded from the tips or edges of leaves, typically occurring at night when transpiration is low, and root pressure builds up. - This process is indeed caused by root pressure, which pushes water up through the plant and out through specialized structures called hydathodes. - Thus, this reason is also **True**. 3. **Evaluating the Relationship**: - Now we need to determine if the reason is the correct explanation of the assertion. - While both statements are true, the reason (guttation due to root pressure) does not explain how transpiration occurs through stomata. Transpiration and guttation are two different processes. - Therefore, the reason is **not the correct explanation** for the assertion. 4. **Conclusion**: - Both the assertion and the reason are true, but the reason does not correctly explain the assertion. - The correct answer is **Option B**: Assertion and Reason are true, but Reason is not the correct explanation of the Assertion.
