Conjunctivitis is an infection primarily related to ______.

Eye

The correct answer is Option (3) -Eye

Conjunctivitis, commonly known as "pink eye," is an infection primarily related to the eye. It affects the conjunctiva, which is the thin, transparent membrane that covers the white part of the eyeball and lines the inside of the eyelids.

This infection can be caused by bacteria, viruses, or allergens. Symptoms include redness of the eye, itchiness, excessive tearing, discharge, and sometimes blurred vision. Conjunctivitis can be highly contagious, especially in cases caused by viruses or bacteria, and it can spread through direct contact with infected individuals or contaminated surfaces.
