A. Coxsackievirus
B. Enterovirus
C. Herpes simplex virus
D. Herpes zoster virus

**Core Concept:** Conjunctivitis is an inflammation of the conjunctiva, the transparent membrane that covers the sclera (white part of the eye) and the inner surface of the eyelids. Enteroviruses are a group of RNA viruses that cause a wide range of diseases, including conjunctivitis.

**Why the Correct Answer is Right:** Coxsackievirus is a member of the Enterovirus species, which is known to cause various infections, including conjunctivitis. Among the given options, Coxsackievirus is the correct choice because it is the specific enterovirus species responsible for conjunctivitis.

**Why Each Wrong Option is Incorrect:**

B. Enterovirus (Option B) is a broad category that includes Coxsackievirus, but it is too general and does not specify the virus causing conjunctivitis.

C. Herpes simplex virus (HSV) usually causes herpes labialis (cold sores) and herpes genitalis, not conjunctivitis.

D. Herpes zoster virus (VZV) is responsible for herpes zoster, also known as shingles, and not conjunctivitis.

**Clinical Pearl / High-Yield Fact:** Coxsackievirus can also cause other conditions, such as hand, foot, and mouth disease, and cardio-vascular diseases like myocarditis and pericarditis. It is essential for medical students and healthcare professionals to recognize the specific pathogens causing various infections to appropriately diagnose and manage the patients.
