Solution

The correct option is A Calcium
Calcium ions bind to troponin and cause the tropomyosin to free the actin filament to join with the myosin head in order for the muscle to contract.
Similarly, when the signal for contraction is stopped, the calcium ion leaves troponin and the muscle relaxes.
