A Correct answer
Explanation

Cardiac output is defined as the volume of blood pumped by each ventricle per minute, calculated as the product of heart rate (beats per minute) and stroke volume (blood pumped per beat). Option B is nonsensical, C lacks the formula, and D describes stroke volume, not cardiac output.
