Among the options provided, the pine tree is the correct choice, as it requires wind for fertilization to occur.
Pine trees are gymnosperms, and they reproduce using seeds produced in cones. Their pollen is lightweight and is carried by the wind to reach the ovules for fertilization.
In contrast:
- Ferns reproduce via spores and do not require fertilization in the same way as seed plants.
- Rosebushes are angiosperms and typically rely on insects or other animals for pollination, not wind.
- Lily flowers also tend to rely on insects or other animals for pollination rather than wind.
So, the best answer is pine tree.
