An infection of the eyes that is highly contagious.

• A. Conjunctivitis
• B. Pink Eye
• C. Glaucoma
• D. Both A and B

Answer: (D)

The idea being tested is that a contagious eye infection is described both by its medical term and by a common name. Conjunctivitis is inflammation of the conjunctiva caused by viral or bacterial pathogens, which makes it highly contagious and easy to spread. “Pink eye” is just the everyday name people use for the same condition. Because both terms refer to the same contagious infection, recognizing them together is the best choice. Glaucoma, on the other hand, is not an infection and is not contagious; it’s a condition involving increased pressure in the eye that affects the optic nerve.
