Select the incorrect statements from the following

Options

A. All subaerial stem modifications are useful for vegetative propagation
B. Underground stem modifications help in vegetative propagation
C. In Agave vegetative buds store food materials and help in vegetative propagation.
D. Axillary bud is present in the axil of petiole in both simple and compound leaves

Answer

To solve the question of selecting the incorrect statements, we will analyze each statement provided in the context of the morphology of flowering plants, particularly focusing on sub-aerial stem modifications and axillary buds.

### Step-by-Step Solution:

1. **Understanding Sub-aerial Stem Modifications**:
- Sub-aerial stems are modifications of the stem that grow just above the soil surface. They are often used for vegetative propagation.
- **Statement 1**: "All sub-aerial stem modifications are useful for vegetative propagation."
- This statement is generally correct as many sub-aerial stems (like runners and stolons) do facilitate vegetative propagation.

2. **Analyzing Agave and Vegetative Buds**:
- Agave plants have vegetative buds that store food and can help in propagation.
- **Statement 2**: "In agave, the vegetative buds store food materials and help in vegetative propagation."
- This statement is also correct. Agave does have vegetative buds that serve this purpose.

3. **Understanding Axillary Buds**:
- Axillary buds are located in the axil of leaves, which is the angle between the leaf and the stem.
- **Statement 3**: "Auxiliary bud, simple and compound, we will get in the axil of petiole of both types of leaves."
- This statement is incorrect. Axillary buds are found in the axil of the entire leaf, not in individual leaflets of a compound leaf. Leaflets do not have axillary buds; only the whole leaf does.

4. **Conclusion**:
- The incorrect statement is **Statement 3**. It misrepresents the location of axillary buds in relation to simple and compound leaves.

### Final Answer:
The incorrect statement is: "Auxiliary bud, simple and compound, we will get in the axil of petiole of both types of leaves."
