Final answer:
Excessive earwax production or failure to regularly clear the ear can lead to a wax buildup or impacted earwax, which can cause various symptoms like hearing loss and earache. While foreign bodies can contribute to this issue by blocking earwax from naturally exiting the ear canal, the correct answer to the question is wax.
Step-by-step explanation:
The question asks what can get stuck in the ear, leading to wax buildup. The correct answer is c) Wax. Naturally, our ears secrete wax as a way to protect and clean the ear canal. This substance traps dust, dead skin cells, and other small particles to prevent them from reaching the sensitive areas of the ear. However, when wax is produced in excessive amounts or is not cleared away regularly, it can accumulate and form a blockage. This condition, known as wax buildup or impacted earwax, can cause hearing loss, earache, and other symptoms. Foreign bodies, such as cotton swabs, beads, or small toys, can also get stuck in the ear and contribute to wax accumulation by impeding the natural migration of earwax out of the ear canal.
