**Core Concept**
The vestibular system plays a crucial role in maintaining balance and spatial orientation. The destruction of the labyrinth, which houses the vestibular apparatus, can disrupt this balance and lead to abnormal eye movements. Nystagmus is a type of involuntary eye movement that can result from damage to the vestibular system.

**Why the Correct Answer is Right**
When the right labyrinth is destroyed, the sensory input from the vestibular apparatus is disrupted. This leads to a mismatch between the sensory input from the intact left labyrinth and the visual input from the environment. The brain attempts to compensate for this mismatch by making corrective eye movements, resulting in nystagmus. The direction of nystagmus is typically towards the side of the damaged labyrinth, as the brain tries to suppress the abnormal input from the damaged side.

**Why Each Wrong Option is Incorrect**
**Option A:** Nystagmus to the left would be incorrect, as the brain would not suppress the input from the intact left labyrinth.
**Option B:** Nystagmus to the right would be incorrect, as the brain would not suppress the input from the intact left labyrinth.
**Option C:** This option is not provided.

**Clinical Pearl / High-Yield Fact**
A classic mnemonic to remember the direction of nystagmus is "opposite to the side of the lesion." This means that if the right labyrinth is destroyed, the nystagmus will be directed to the left.

**Correct Answer: C. to the left.**
