Bell's Palsy causes facial muscles to be very weak or totally paralyzed.

• A. Facial muscles are very weak or totally paralyzed
• B. Brain tumor
• C. Inflammation of meninges
• D. Seizures

Answer: (A)

Bell's Palsy is a condition where the facial nerve (cranial nerve VII) becomes inflamed or compressed, leading to sudden weakness or paralysis of the muscles used for facial expression on one side. The statement that facial muscles are very weak or totally paralyzed directly describes this hallmark effect, making it the best fit for Bell's Palsy. Other options describe different problems: a brain tumor can cause various neurologic changes but isn’t defined by sudden unilateral facial paralysis; inflammation of the meninges (meningitis) brings symptoms like fever, neck stiffness, and headache; seizures involve episodes of abnormal brain activity and convulsions. The specific unilateral facial weakness/paralysis points to Bell's Palsy.
