Solution

The correct option is B respiratory tract
Pneumonia is caused by bacteria that enters the body through the respiratory tract. When an infection spreads to the lungs, inflammation causes the alveoli, or air sacs, to fill with fluid or pus. This can cause breathing problems, coughing, and the production of yellow or brown mucus. It's possible that breathing will become more difficult or shallow.
