Pseudohypertrophy is due to replacement of muscle by which tissue?

Explanation:
Pseudohypertrophy occurs when muscle fibers are lost and replaced by noncontractile tissue, making the muscle look larger without gaining true muscle strength. In many muscular dystrophies, especially Duchenne, the damaged muscle is infiltrated by fat and fibrous (connective) tissue. This fibrofatty replacement enlarges the muscle externally but weakens its function, because the new tissue cannot contract. Therefore, the tissue replacing the muscle is both adipose (fat) tissue and fibrous connective tissue.
