D Correct answer
Explanation

Mitochondria are the powerhouses of the cell and the site of cellular respiration. They produce ATP through aerobic respiration using the Krebs cycle and electron transport chain. Endoplasmic reticulum handles protein synthesis, Golgi body modifies and packages proteins, and lysosomes digest waste - none of these perform cellular respiration.
