Explanation:

The mitochondria are the power - houses of the cell. The aerobic phase of cellular respiration, including the Krebs cycle and oxidative phosphorylation, which generate ATP for muscle contraction and other cellular processes, occurs in the mitochondria. The nucleus contains genetic material, the sarcoplasmic reticulum stores calcium in muscle cells, and myofibrils are the contractile elements of muscle cells but do not host the aerobic phase of cellular respiration.

Answer:

C. mitochondria
