The correct Answer is:
To identify the correct statements among the given options, we will analyze each statement one by one. ### Step-by-Step Solution: 1. **Statement I: Runners are underground in strawberry and all grasses.** - Runners are a type of stem modification that allows vegetative propagation. In strawberries, runners (or stolons) are indeed above ground. While some grasses do have underground stems, it is incorrect to say that all grasses have underground runners. Therefore, this statement is **incorrect**. 2. **Statement II: In pineapple, the lateral branches originate from the basal and underground portion of the main stem and initially grow horizontally beneath the soil.** - This statement describes the process of vegetative propagation in pineapple accurately. The lateral branches, known as suckers, do originate from the basal nodes and grow horizontally underground before emerging above the soil. Thus, this statement is **correct**. 3. **Statement III: Floral buds in Agave help in vegetative propagation.** - In Agave, floral buds can develop into bulbils, which are used for vegetative propagation. This is a true statement, as Agave can reproduce both sexually through flowers and asexually through bulbils. Therefore, this statement is **correct**. 4. **Statement IV: Axillary bud is absent in the axil of leaflets present in both pinnately and palmately compound leaves.** - This statement is incorrect. In both pinnately and palmately compound leaves, axillary buds are typically present in the axils of the leaflets. Therefore, this statement is **incorrect**. ### Conclusion: - The correct statements are **II and III**. - Therefore, the answer is that statements II and III are correct.
