Which is a muscular dystrophy?

• A. Tendonitis
• B. Myasthenia Gravis
• C. Muscular Dystrophy
• D. Duchenne MD

Answer: (C)

Muscular dystrophy refers to a group of inherited disorders in which skeletal muscles progressively weaken and waste away. The term itself names the category being asked about, so it directly matches the idea of a dystrophic muscle disease. Tendonitis is just inflammation of a tendon, not a dystrophy. Myasthenia gravis affects the nerve-muscle signaling at the neuromuscular junction and isn’t a degenerative muscle disease. Duchenne muscular dystrophy is a specific form within this category caused by dystrophin deficiency; it’s indeed a muscular dystrophy, but the question is pointing to the broad category, which is why the broad term is the best fit.
