D Correct answer
Explanation

The typical cardiac output for a healthy adult at rest is 5-6 liters per minute. This represents the total volume of blood pumped by both ventricles combined. Values of 1-4 liters are too low for normal cardiac function. The heart pumps approximately 70-80 mL per beat, and at 70 beats per minute, this equals about 5 liters per minute.
