Answer 1

The correct option is A

To prevent dust particles from entering the nasal cavity

Nasal hair is the hair inside the nose. It is one of the body's first line of defence against harmful environmental pathogens such as germs, fungus, and spores that are inhaled. Another purpose of nasal hair is to provide additional humidity to the inhaled air. As the air passes through nasal passages, the mucus and hair provide heat and moisture.
