Answer:
Option (A).
Explanation:
Muscle contraction may be defined as the physiological process of the activation of tension generating sites that occur within the muscle fibers. Actin, myosin, troponin and other proteins are important for muscle contraction.
The calcium ion is important for the muscle contraction. The binding of calcium with troponin causes the movement of tropomyosin out of the grooves between the actin molecules during muscle contraction.
Thus, the correct answer is option (A).
