Which of the following is a common symptom of myasthenia gravis?

Explanation:
Myasthenia gravis causes fatigable weakness of voluntary muscles due to impaired neuromuscular transmission. The eyelid and eye muscles are commonly affected first, so ptosis is a frequent presenting symptom. The weakness tends to worsen with use and improve with rest or acetylcholinesterase inhibitors, which helps explain why eyelid drooping can fluctuate. Seizures, aphasia, and hearing loss are not typical features of MG, as they involve brain activity, language centers, or the auditory system rather than the neuromuscular junction.
