Entomophily is present in :-

Options

A. Wheat
B. Sunflower
C. Rice
D. All of the above

Answer

To determine which plant exhibits entomophily, we need to analyze the pollination method of each option provided:

1. **Understanding Entomophily**:
- Entomophily refers to the pollination process where insects are the primary pollinators. This means that the plants involved attract insects, which then facilitate the transfer of pollen from the male parts (anthers) to the female parts (stigmas) of the flowers.

2. **Analyzing the Options**:
- **Option A: Wheat**:
- Wheat is primarily wind-pollinated (anemophily). The pollen grains are lightweight and can be carried by the wind, making it unsuitable for entomophily.
- **Option B: Sunflower**:
- Sunflowers are known to attract insects, particularly bees and butterflies, due to their nectar and bright colors. This makes them a prime example of entomophily.
- **Option C: Rice**:
- Similar to wheat, rice is also wind-pollinated. It does not rely on insects for pollination, thus it does not represent entomophily.
- **Option D: All of the above**:
- Since only sunflower is pollinated by insects, this option is incorrect.

3. **Conclusion**:
- Based on the analysis, the only plant that exhibits entomophily is **sunflower** (Option B).

### Final Answer:
The correct answer is **B: Sunflower**.
