The correct answer is: B
Explanation
The external openings of the nasal cavity that admit air to the lungs are called nostrils. The oesophagus is a tube that connects the throat to the stomach. The larynx, also known as the voice box, is involved in breathing, producing sound, and protecting the trachea against food aspiration. The trachea, also known as the windpipe, is a tube that connects the pharynx and larynx to the lungs, allowing the passage of air.
