Answer: Option D.

D) Every student had an elevated heart rate during exercise.

Explanation:

The students have elevated heart rates during exercise. This is because during exercise, muscles need 3 times or four times oxygen when you exert yourself. During exercise, the heart beat faster which make for quicker pulse so that more blood is pump out of you body. The heart beat both stronger and faster to increase cardiac output during exercise.

Cardiac output is stroke volume * heart rate.

Stroke volume is the amount of blood pumped by the heart. when the heart beats.

Heart rate is the number of times heart beats per minutes.
