Answer 1

c. Bronchiole

They will branch all the way to terminal bronchiole before they go into alveoli

Answer 2

The correct answer is option c. "bronchiole".

Step-by-step explanation:

The passage of airway within the lungs is known as bronchus. However, air exchange does not happen in the bronchus, it happens in small air sacs named alveoli. The smaller versions of the bronchus are known as the bronchiole, which branches further until it becomes the alveoli, the structure at which air exchange takes place.
