Solution

The correct option is A Nostril - Nasal cavity - Pharynx - Larynx - Trachea - Bronchi -Bronchioles - Alveoli
Breathing starts at the nose and mouth, we inhale air into our nose or mouth, and it travels down the back of our throat and into our windpipe, or trachea. Your trachea then divides into air passages called bronchial tubes. As the bronchial tubes pass through the lungs, they divide into smaller air passages called bronchioles. The bronchioles end in tiny balloon-like air sacs called alveoli. Your body has over 300 million alveoli. So, the correct answer is B. ( Nostril - Nasal cavity - Pharynx - Larynx - Trachea - Bronchi -Bronchioles - Alveoli )
