The correct Answer is:
To answer the question regarding the characteristics related to the bulb of an onion, we will analyze each option provided: 1. **Option A: Discoid stem storing food** - The bulb of the onion is indeed a modified stem that is swollen and disc-shaped. This modification allows the stem to store food, which is a characteristic of bulbs in the lily family. Therefore, this statement is correct. 2. **Option B: Fleshy storage leaves** - The bulb consists of fleshy leaves that store the reserve food materials. These leaves overlap and form the bulb structure, which is essential for the onion's survival and growth. Thus, this statement is also correct. 3. **Option C: Radical leaves** - The term "radical leaves" refers to leaves that arise from the base of the stem or from the roots. In onions, leaves do emerge from the base of the bulb, making this statement correct as well. 4. **Option D: Axillary bud helps in vegetative propagation** - The bulb of the onion contains axillary buds that can give rise to new plants through vegetative propagation. This is a typical characteristic of bulbs, allowing them to reproduce asexually. Therefore, this statement is also correct. In conclusion, all the options (A, B, C, and D) are characteristics related to the bulb of the onion. **Final Answer:** All the options are correct (A, B, C, D). ---
