The correct option is A Nostrils
Nose is the entry point of air into the body. From the nasal cavity, air enters the bronchi and to the lungs. Lungs have alveoli which is associated with blood capillaries. The oxygen in the alveoli diffuses into the capillary and the carbondioxide in the blood diffuses back into the capillary and eventually exhaled out.
