A patient presents with a sudden onset of speech difficulties, specifically difficulty comprehending spoken and written language, despite being able to speak fluently but nonsensically. Which area of the brain is most likely affected?

✓ Correct Answer: Option B

Wernicke's area, typically located in the superior temporal gyrus of the dominant hemisphere, is crucial for language comprehension. Damage to this area results in fluent aphasia with impaired comprehension and often nonsensical speech.
