Answer

To determine the correct answer for the question "A plant bearing solitary flowers is," we will analyze each option provided.

### Step-by-Step Solution:

1. **Understanding Solitary Flowers**:
- A solitary flower is one that arises individually at a specific position on the plant, such as the terminal or axillary region. It can also appear in groups but is separated by vegetative regions.

2. **Analyzing the Options**:
- **Option A: Verticillaster**:
- This is an inflorescence type where flowers are arranged in whorls. It does not describe solitary flowers, as they are grouped in a circular arrangement.

- **Option B: Scyathium**:
- A Scyathium is a type of inflorescence that consists of a cup-like structure formed by bracts. It can bear solitary flowers or several flowers separated by vegetative regions. This fits the description of a plant bearing solitary flowers.

- **Option C: Spike**:
- In a spike, flowers are directly attached to the main axis without pedicels. This arrangement does not emphasize solitary flowers, as they are clustered closely together.

- **Option D: Catkin**:
- A catkin is a cylindrical flower cluster that typically lacks petals. This structure also does not represent solitary flowers, as it consists of multiple flowers grouped together.

3. **Conclusion**:
- After analyzing all the options, the best fit for a plant bearing solitary flowers is **Option B: Scyathium**. Although it can have multiple flowers, it can also bear solitary flowers, making it the correct answer.

### Final Answer:
The plant bearing solitary flowers is **Scyathium** (Option B).
