The correct answer is A. Cardiovascular Endurance.
Explanation
Cardiovascular endurance is the ability to perform physical work efficiently for as long as possible. This capacity can be during aerobic activities in which the type of aerobic route is used, that is, they are those activities of low to moderate intensity, and that last a long time. Second, in anaerobic activities, those that use the anaerobic type of pathway. They are those activities of very high intensity or explosive, and of short duration. These physical activities cause the heart rate to increase because the muscles and other organs and tissues involved need to be oxygenated, so the heart sends oxygenated blood and therefore increases its heart rate. According to the above, Carly and Monique using the jump rope and skates increased their heart rate so they are working on what component of fitness is related to A. Cardiovascular Endurance.
