Solution

The correct option is A a-r, b-s, c-q, d-p
The larynx is another name for the voice box. It's a tube about 2 inches long in adults. It sits above the windpipe in the neck and in front of the food pipe. The trachea, also called as the windpipe, is a  tube that connects the pharynx and larynx to the lungs, allowing the passage of air, and so is present in almost all air-breathing animals with lungs. Alveoli are the air sacs present inside the lungs, these are the site of exchange of gases. The epiglottis is a flap in the throat that keeps food from entering the windpipe and the lungs. The flap is made of elastic cartilage covered with a mucous membrane, attached to the entrance of the larynx.

Hence the correct answer is (A)
