Answer: (D)

Verified step by step guidance

1. Step 1: Understand the question is asking for a common bacterial infection of the eye, so focus on conditions caused by bacteria rather than non-infectious or genetic disorders.
2. Step 2: Review each option: Glaucoma is an eye condition related to increased intraocular pressure, not an infection; Cataract is a clouding of the lens, typically age-related, not infectious; Retinitis pigmentosa is a genetic disorder affecting the retina, not caused by bacteria.
3. Step 3: Recognize that Conjunctivitis, often called 'pink eye,' is an inflammation of the conjunctiva commonly caused by bacterial or viral infections, making it a typical bacterial eye infection.
4. Step 4: Confirm that among the options, Conjunctivitis is the only one that fits the description of a common bacterial infection of the eye.
5. Step 5: Conclude that the correct answer is Conjunctivitis because it is an infectious condition caused by bacteria affecting the eye's conjunctiva.
