Solution

The correct option is B X-Nasal cavity, Y-Larynx, Z-Pharynx

The larynx commonly called the voice box, is an organ in the top of the neck involved in breathing, producing sound and protecting the trachea against food aspiration. The pharynx (plural: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the oesophagus and trachea – the tubes going down to the stomach and the lungs.
The nasal cavity is inside of your nose. It is lined with a mucous membrane that helps keep your nose moist by making mucus so you won't get nosebleeds from a dry nose.
