larynx, bronchus, bronchiole and trachea.

B.

bronchus, bronchiole, trachea and larynx.

C.

D.

larynx, trachea, bronchiole, and bronchus.

Correct answer is D

The parts labelled 1, II, III and IV respectively are larynx, trachea, bronchiole and bronchus
The larynx, commonly known as the voice box, is a cartilaginous structure located in the neck, just below the pharynx and above the trachea.
The trachea, also known as the windpipe, is a long tube made of C-shaped rings of cartilage that extend from the larynx to the bronchi.
Bronchioles are small, narrow tubes that branch out from the bronchi. They represent the smaller airways within the lungs.
The bronchi are the two main branches that arise from the lower end of the trachea, one leading to each lung.
