The correct answer is e. muscular dystrophy

Muscular dystrophy is a group of inherited genetic disorders that cause progressive weakness and degeneration of the muscles. It is characterized by the loss of muscle tissue and weakness, which can lead to difficulty walking, breathing, and other physical activities. There are over 30 different types of muscular dystrophy, each caused by a different genetic mutation. The most common type is Duchenne muscular dystrophy, which affects males and usually appears in early childhood.
