Answer:

The correct answer is option D.

Explanation:

The cardiac output is the blood amount that heart pumps in a minute. In other words, the amount of blood pump by the left ventricle of the heart in a 1 contraction is termed as the stroke volume. The stroke volume and the heart rate determine the cardiac output. Slow heart rate increases the end-diastolic volume, stroke volume, and force of contraction.

Thus, the correct answer is option d.
