**Core Concept**
The underlying principle being tested involves the reactivation of a virus that affects the eye, indicating a focus on **viral pathology** and **ophthalmology**. This question requires knowledge of viruses that can reactivate and cause ocular complications.

**Why the Correct Answer is Right**
The correct answer is related to the **Varicella-Zoster Virus (VZV)**, which is known to reactivate from latency and cause **herpes zoster ophthalmicus** when it involves the eye. This condition can lead to serious ocular complications, including keratitis, uveitis, and retinal necrosis.

**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because it does not typically reactivate to involve the eye in the manner described.
**Option B:** Incorrect as it is not commonly associated with reactivation and ocular involvement.
**Option D:** Incorrect because, although it can cause ocular disease, the pattern of reactivation and involvement is different from what is described.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that **herpes zoster ophthalmicus** can result in significant morbidity if not promptly treated, emphasizing the importance of early recognition and antiviral therapy.

**Correct Answer:** D. Varicella-Zoster Virus
