Options

A. One
B. Two
C. Four
D. Three

Answer

To determine how many plants from the given list are vascular and monoecious, we will analyze each plant based on the definitions provided:

1. **Definitions**:
- **Vascular plants**: Plants that have vascular tissues (xylem and phloem) for the transport of water, nutrients, and food.
- **Monoecious plants**: Plants that have both male and female reproductive organs on the same individual.

2. **List of Plants**:
- Chara
- Pinus
- Cycas
- Sphagnum
- Maize
- Papaya

3. **Analysis of Each Plant**:
- **Chara**:
- Monoecious: Yes
- Vascular: No (it is a green algae)
- **Pinus**:
- Monoecious: Yes
- Vascular: Yes (it is a gymnosperm)
- **Cycas**:
- Monoecious: No (it is dioecious)
- Vascular: Yes (it is a gymnosperm)
- **Sphagnum**:
- Monoecious: Yes
- Vascular: No (it is a moss)
- **Maize**:
- Monoecious: Yes
- Vascular: Yes (it is an angiosperm)
- **Papaya**:
- Monoecious: No (it is dioecious)
- Vascular: Yes (it is an angiosperm)

4. **Conclusion**:
- The plants that are both vascular and monoecious from the list are:
- Pinus
- Maize
- Therefore, there are **2 plants** that are vascular and monoecious.

### Final Answer:
**2 plants are vascular and monoecious (Pinus and Maize).**
