**Option D:** If this option represents an uncommon or unrelated symptom, it might be the correct answer due to its exceptionality.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that **pontine strokes** can have devastating consequences due to the brainstem's critical role in vital functions. Recognizing the signs of **brainstem stroke**, such as sudden onset of symptoms, is crucial for timely medical intervention.
**Correct Answer:** Correct Answer: D.
