Correct Answer: D. Progressive weakness that is worse at the day’s end

Option D: Myasthenia gravis is an autoimmune disease in which antibodies destroy muscle nerve receptors. This causes problems with communication between nerves and muscles resulting in skeletal muscle weakness that worsens during the day.

---

Option A: Ascending paralysis and loss of motor function are symptoms of Guillain Barre syndrome.

Option B: Visual problems such as blurred vision, double vision, or loss of vision are common with multiple sclerosis.
