The correct Answer is:
To solve the question regarding the assertion and reason statements, we will analyze both the assertion (A) and the reason (R) step by step. ### Step-by-Step Solution: **Step 1: Analyze the Assertion (A)** The assertion states that "Runner, tuber, sucker, offset etc. are vegetative propagules." - **Explanation**: Vegetative propagules are structures that allow plants to reproduce asexually. Runners (like in strawberries), tubers (like in potatoes), suckers (like in pineapples), and offsets (like in water hyacinth) are all examples of such structures. They can develop into new plants without the need for seeds. **Step 2: Determine the Truth of the Assertion (A)** - The assertion is **True** because all the mentioned structures are indeed vegetative propagules used in asexual reproduction. **Step 3: Analyze the Reason (R)** The reason states that "Two parents are involved in the formation of these structures." - **Explanation**: In vegetative propagation, a single parent plant gives rise to new plants through modifications of its structures. This process does not involve two parents; it is a form of asexual reproduction. **Step 4: Determine the Truth of the Reason (R)** - The reason is **False** because vegetative propagation involves only one parent, not two. **Step 5: Conclusion** - Since the assertion is true and the reason is false, the correct relationship between the assertion and reason is that the assertion is true while the reason is false. ### Final Answer: The correct option is that the assertion is true and the reason is false. ---
