Plants with ovaries having only one or a few ovules are generally pollinated by

Options

A. bees
B. butterflies
C. birds
D. wind

Explanation

To solve the question "Plants with ovaries having only one or a few ovules are generally pollinated by," we will analyze the options and the characteristics of different types of pollination.

### Step-by-Step Solution:

1. **Understanding the Types of Pollination**:
- Pollination can occur through various agents, including insects (like bees and butterflies), birds, and wind.
- Each type of pollination has specific characteristics and is associated with certain types of plants.

2. **Identifying Insect Pollination (Entomophily)**:
- Insect pollination, known as entomophily, is typically associated with flowers that have multiple ovules.
- This type of pollination is efficient and has a high success rate for fertilization.

3. **Identifying Bird Pollination (Ornithophily)**:
- Bird pollination, known as ornithophily, is also associated with flowers that may have a few ovules.
- Birds are attracted to brightly colored flowers and those that produce nectar.

4. **Identifying Wind Pollination (Anemophily)**:
- Wind pollination is known as anemophily and is characterized by plants that have feathery stigmas and produce a large amount of pollen.
- These plants often have few ovules, and the chances of successful fertilization are lower compared to insect and bird pollination.

5. **Conclusion**:
- Given that the question specifies plants with ovaries having only one or a few ovules, the most likely pollination agent is birds (ornithophily).
- Therefore, the correct answer is **birds**.

### Final Answer:
Plants with ovaries having only one or a few ovules are generally pollinated by **birds**.
