Why does the body cough if particles get trapped in the trachea?
Answer and explanation
Correct answer: To clear the air passage
The trachea is an air passage leading toward the bronchi and lungs. Its lining helps trap dust and other particles in mucus. A cough is a protective reflex that produces a forceful outward flow of air, helping dislodge and expel the irritant so breathing remains easier. Thus option A is correct; the other options refer to digestion, excretion, or plant transpiration.
