Explanation:

Conductive hearing loss occurs when sound is blocked from reaching the inner ear. Earwax buildup is a common, reversible blockage in the ear canal, making it the most frequent cause. Loud noise and age typically cause sensorineural loss, while genetic factors are less common for conductive loss.

C. Earwax buildup
