The correct Answer is:
To solve the question regarding the assertion and reason, we will analyze both statements step by step. ### Step-by-Step Solution: 1. **Understanding the Assertion**: - The assertion states that "Air layering is commonly done in woody shrubs and trees." - This statement is true because air layering is indeed a common method of vegetative propagation used for woody plants. It allows for the production of new plants while still attached to the parent plant. 2. **Understanding the Reason**: - The reason given is "They do not bear the bending branches near the ground." - This statement is also true, as many woody shrubs and trees do not have branches that naturally bend down to the ground. However, this reason does not adequately explain why air layering is performed on these plants. 3. **Analyzing the Relationship**: - While both the assertion and the reason are true, the reason does not provide a correct explanation for the assertion. Air layering is used to propagate plants that may not have branches that can easily root in the ground, but the lack of bending branches is not the primary reason for using air layering. 4. **Choosing the Correct Option**: - Given the analysis, we can conclude that: - Both the assertion and the reason are true. - The reason is not the correct explanation for the assertion. - Therefore, the correct option is: "Both assertion and reason are true and reason is not the correct explanation of assertion." ### Final Answer: The correct option is: **Both assertion and reason are true and reason is not the correct explanation of assertion.** ---
