**Core Concept**
Ramsay Hunt syndrome is a rare neurological disorder characterized by facial paralysis, ear pain, and an eruption of herpes zoster in the ear. The syndrome is caused by the reactivation of the varicella-zoster virus, which remains dormant in the geniculate ganglion of the facial nerve.

**Why the Correct Answer is Right**
Ramsay Hunt syndrome occurs when the varicella-zoster virus reactivates in the geniculate ganglion, causing inflammation and damage to the facial nerve. This leads to symptoms such as facial paralysis, ear pain, and a rash in the ear. The syndrome is often accompanied by vertigo, hearing loss, and tinnitus. The diagnosis is typically made clinically, and treatment may involve antiviral medication and corticosteroids.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because Ramsay Hunt syndrome is indeed characterized by facial paralysis, which is caused by the inflammation and damage to the facial nerve.
**Option B:** This option is incorrect because Ramsay Hunt syndrome is indeed caused by the reactivation of the varicella-zoster virus, which remains dormant in the geniculate ganglion of the facial nerve.
**Option C:** This option is incorrect because Ramsay Hunt syndrome is indeed accompanied by ear pain, which is caused by the inflammation of the auricular branch of the trigeminal nerve.

**Clinical Pearl / High-Yield Fact**
Ramsay Hunt syndrome is often misdiagnosed as Bell's palsy, but the presence of a rash in the ear and ear pain are key distinguishing features. A high index of suspicion and a thorough examination of the ear are essential for an accurate diagnosis.

**Correct Answer: A.**
