**Core Concept**
The question is testing the understanding of the anatomy of the trigeminal nerve (cranial nerve V), particularly its distribution and the phenomenon of crossed innervation in the context of herpes zoster.

**Why the Correct Answer is Right**
Herpes zoster involving the tip of the nose is most likely to affect the eye due to the involvement of the nasociliary branch of the ophthalmic division (V1) of the trigeminal nerve. This branch supplies the skin of the nose, including the tip, and also gives off the anterior ethmoidal and posterior ethmoidal nerves, which supply the nasal septum and lateral wall of the nasal cavity. Additionally, the nasociliary branch gives off the long ciliary nerves, which innervate the ciliary body and iris of the eye. This crossed innervation allows herpes zoster to spread from the skin of the nose to the eye, resulting in ophthalmic involvement.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not relevant to the question and does not provide a plausible explanation for the involvement of the eye.
* **Option B:** This option is incorrect because the maxillary division (V2) of the trigeminal nerve primarily supplies the palate, nasal cavity, and maxilla, but not the tip of the nose.
* **Option C:** This option is incorrect because the mandibular division (V3) of the trigeminal nerve primarily supplies the lower face, including the jaw, but not the tip of the nose.

**Clinical Pearl / High-Yield Fact**
In herpes zoster ophthalmicus, the presence of vesicles in the distribution of the nasociliary branch, particularly the area around the eye, is a red flag for potential ocular involvement and requires prompt ophthalmologic evaluation.

**Correct Answer: B. The maxillary division (V2) of the trigeminal nerve primarily supplies the palate, nasal cavity, and maxilla, but not the tip of the nose.
