Answer:
air brone
Explanation:
The most common allergens are pollens from wind-pollenated plants, such as trees, grasses, and weeds. The pollens from insect-pollinated plants are too heavy to remain airborne for long, and they're less likely to trigger an allergic reaction. Hay fever comes by its name from hay-cutting season.
