Correct Answer
Option A
Detailed Explanation
Stroke volume is defined as the amount of blood pumped by each ventricle per heartbeat, while cardiac output is indeed the product of stroke volume and heart rate. The sino-atrial node is a specialized tissue responsible for generating impulses, and the QRS complex corresponds to the electrical excitation of the ventricles.
