Final answer:
The correct answer is Bell's palsy.
Step-by-step explanation:
The correct answer is B) Bell's palsy.
Bell's palsy is caused by the unilateral paralysis of cranial nerve VII, also known as the facial nerve. This condition leads to the sudden weakness or paralysis of the muscles on one side of the face. It can result in facial drooping, difficulty closing one eye, and trouble with facial expressions.
For example, if a person with Bell's palsy tries to smile, the affected side of their face may not move, while the unaffected side will. This condition is usually temporary and resolves on its own within a few weeks or months.
