b. exhaustion level.
c. sweat rate.
d. heart rate.
Heart rate is the most accurate of the metrics available for measuring the effectiveness of exercise. Therefore, the correct option is D.
Heart rate is a useful indicator of the circulatory response to physical activity and can give an indication of the degree of physical exertion. Heart rate increases during activity to meet the body's oxygen and energy needs. Cardiovascular workload increases with exercise-induced heart rate.
To achieve specific fitness goals, people can set their exercise intensity and monitor their heart rate to ensure they are working within their target heart rate zone. Improvement in heart rate, or the speed at which heart rate returns to normal after exercise, can potentially reveal information about cardiovascular fitness.
Therefore, the correct option is D.
