The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks about a condition characterized by the progressive degeneration of skeletal muscle, primarily due to a genetic disorder. 2. **Analyzing the Options**: - **A. Myasthenia Gravis**: This is an autoimmune disorder that affects the neuromuscular junction, leading to muscle weakness and fatigue, but it is not primarily a genetic disorder. - **B. Muscular Dystrophy**: This is a genetic disorder that leads to progressive degeneration of skeletal muscle due to the lack of dystrophin protein, making muscle fibers more susceptible to damage. - **C. Tetanus**: This condition is caused by low blood calcium levels and is characterized by muscle spasms, not degeneration of skeletal muscle. - **D. Arthritis**: This is an inflammatory condition affecting joints, not skeletal muscles, and is not primarily a genetic disorder. 3. **Identifying the Correct Answer**: Among the options, muscular dystrophy is the only condition that fits the description of progressive degeneration of skeletal muscle due to a genetic disorder. 4. **Conclusion**: The correct answer to the question is **B. Muscular Dystrophy**. ---
