Choose the dry fruits developed from unilocular ovaries
I) Pepo II) Drupe of mango
III) Cypsela IV) Nut
V) Legume

Options

A. I to V
B. II to V
C. III to V
D. IV and V only

Answer

To determine which dry fruits are developed from unilocular ovaries, we need to analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding Dry Fruits**:
- Dry fruits are those where the pericarp (the fruit wall) is dry at maturity. They do not have fleshy parts like mesocarp or endocarp.

2. **Identifying Unilocular Ovaries**:
- A unilocular ovary is one that has a single locule or chamber, which means it contains only one ovule or seed.

3. **Analyzing Each Option**:
- **I) Pepo**:
- A pepo is a type of fleshy fruit, typically found in cucurbits like watermelon and cucumber. It develops from a multi-locular ovary, so this is not a dry fruit.
- **II) Drupe of Mango**:
- A drupe is a fleshy fruit with a hard stony endocarp (like a peach or mango). It has multiple layers (epicarp, mesocarp, endocarp) and is not a dry fruit.
- **III) Cypsela**:
- A cypsela is a dry fruit that develops from a unilocular ovary. It is typically one-seeded and does not split open at maturity (e.g., dandelion seeds).
- **IV) Nut**:
- A nut is a hard-shelled dry fruit that usually contains a single seed. It also develops from a unilocular ovary and does not split open at maturity.
- **V) Legume**:
- A legume is a dry fruit that develops from a unilocular ovary and typically contains multiple seeds. It does split open along two seams at maturity, but it is still classified as a dry fruit.

4. **Conclusion**:
- The dry fruits that develop from unilocular ovaries are **Cypsela (III)**, **Nut (IV)**, and **Legume (V)**. Therefore, the correct answer is options **III, IV, and V**.

### Final Answer:
The dry fruits developed from unilocular ovaries are **III) Cypsela, IV) Nut, and V) Legume**.
