Progressive degeneration of skeletal muscle is mostly due to genetic disorder of A Tetany B Gouty arthritis C Myasthenia gravis D Muscular dystrophy
Option D. Muscular dystrophy is a group of inherited muscle diseases in which muscle fibers are unusually susceptible to damage. It is characterized by progressive skeletal muscle degeneration, defects in muscle proteins and the death of muscle cell and tissue. Hence progressive degeneration of skeletal muscle, mostly due to genetic disorder occurs in muscular dystrophy. So, the correct answer is 'Muscular dystrophy'.
