**Core Concept**
Meniere's disease is a disorder of the inner ear that affects balance and hearing. It is characterized by a triad of symptoms: vertigo, tinnitus, and hearing loss. The exact cause of Meniere's disease is unknown, but it is thought to be related to an abnormality in the endolymphatic fluid of the inner ear.

**Why the Correct Answer is Right**
Pulsatile tinnitus, which is characterized by a rhythmic or pulsating sound in the ear, is not typically associated with Meniere's disease. The tinnitus in Meniere's disease is usually described as a low-frequency, unilateral, and fluctuating sound. This is in contrast to pulsatile tinnitus, which is often related to vascular abnormalities or other conditions not directly related to Meniere's disease. The inner ear abnormalities seen in Meniere's disease do not typically cause pulsatile tinnitus.

**Why Each Wrong Option is Incorrect**
**Option A:** Sensorineural deafness is a typical feature of Meniere's disease, as it is characterized by a progressive, fluctuating sensorineural hearing loss.
**Option B:** Vertigo, or a feeling of spinning or dizziness, is a classic symptom of Meniere's disease and is often the most distressing symptom for patients.
**Option D:** Fluctuating deafness is also a hallmark of Meniere's disease, with patients often experiencing episodes of hearing loss that vary in severity.

**Clinical Pearl / High-Yield Fact**
Meniere's disease is often associated with a classic triad of symptoms: vertigo, tinnitus, and hearing loss. However, it's essential to note that not all patients will experience all three symptoms, and the severity of the symptoms can vary widely between individuals.

**✓ Correct Answer: C. Pulsatile tinnitus**
