Pseudohypertrophy in DMD refers to enlargement of which muscles due to fat and connective tissue replacement?

Explanation:
Pseudohypertrophy arises when muscle tissue is lost and replaced by fat and connective tissue. In Duchenne muscular dystrophy, this fatty/fibrous replacement most prominently affects the calf muscles (the gastrocnemius and often the soleus), so the calves appear enlarged even though the muscle is weaker. This swollen appearance is due to the noncontractile tissue taking the place of muscle fibers, not from true muscle growth. The other muscles listed aren’t the classic sites for this fatty replacement pattern in DMD.
