- **B) Entomophilia**: This term refers to pollination that occurs with the help of insects. This does not involve air transfer, so it is incorrect.
- **C) Zoophily**: This term refers to pollination by animals. Again, this does not involve air transfer, making it incorrect.
- **D) Malakophilia**: This term refers to pollination by snails. This is also not related to air transfer, so it is incorrect.

4. **Conclusion**: After analyzing all the options, the correct answer is **A) Anemophilia**, as it specifically refers to the phenomenon of pollen grains being transferred to the stigma by air.

**Final Answer**: The phenomenon of pollen grains being transferred to stigma by air is called **Anemophilia**.
