Group of hereditary diseases characterized by degeneration of muscle and weakness.

Explanation:
Muscular dystrophy refers to a group of inherited disorders in which mutations affect the proteins that support muscle fibers, leading to progressive muscle weakness and degeneration. The word dystrophy signals defective development or maintenance of tissue, and in these conditions the muscles waste away over time, causing increasing disability. This matches the description in the question. In contrast, cystic fibrosis primarily involves thick mucus affecting the lungs and digestive system; dementia is a cognitive decline condition; and hepatitis is inflammation of the liver—none of these describe inherited muscle degeneration.
