Answer:
Option). about 20 percent of the calcium ion required for contraction comes from outside the cell. 
Explanation:
Calcium ions play an important role in cardiac muscle physiology. Calcium ions influx is responsible for plateau phase after depolarization. Calcium ions also play role in muscle contraction with the help of troponin (regulatory protein).
