The correct answer is: Increased heart rate.
Heart rate represents the speed at which the heart performs the function of pumping blood into the arteries. If a person has extensive blood loss, then the best compensatory response would be an increased heart rate. This is because if the heart rate increases, blood will be pumped into the arteries at a faster rate. Thus, the blood loss will be compensated faster.
