Solution

The correct option is C Bronchioles
The lungs which form the main respiratory system is a pair of spongy, air-filled organs which is located on either side of the chest in the rib cage. The inhaled air passes through the trachea (windpipe) into the lungs through its tubular branches known as bronchi which further divide into numerous smaller tubes known as the bronchioles.
