Solution

The correct option is D
$N o s t r i l s \to p h a r y n x \to l a r y n x \to t r a c h e a \to a l v e o l i$

The air enters through nostrils, passes to the pharynx, then to the larynx, trachea and then to alveoli. As soon as the air is inhaled, the diaphragm and intercostal muscles contract. Meanwhile, there is also the expansion of thoracic muscles which creates enough space for the air to enter into the lungs. In the lungs, the exchange of gases takes place and carbon dioxide is exhaled out.
