Final answer:
The question asks who would have a higher pulse pressure among a resting athlete and a resting lazy person. Generally, all individuals at rest would have similar pulse pressures unless they have underlying cardiovascular conditions. After exercise, an athlete may show a temporarily higher pulse pressure due to increased stroke volume. Therefore, the correct option is D.
Step-by-step explanation:
Pulse pressure is the difference between the systolic and diastolic blood pressures. It is an indicator of the health of your arteries and heart. A normal resting pulse pressure is usually between 30-40 mm Hg. A high or wide pulse pressure is often seen following strenuous exercise due to an increase in stroke volume. Chronic high resting pulse pressures can indicate health issues and require medical treatment.
Comparing a resting athlete versus a resting lazy person, the athlete is likely to have a better-conditioned cardiovascular system, which may actually result in a lower resting pulse pressure because their heart is more efficient. Thus, in the absence of strenuous exercise or other conditions, all the individuals (A, B, and C) would generally have the same pulse pressure, provided they are in a state of rest and do not have any underlying cardiovascular conditions.
However, if the question is referring to what would happen after exercise, the athlete might display a temporarily higher pulse pressure. This increase would be due to a more significant rise in the stroke volume as a result of their better conditioning and ability to handle strenuous exercise. But it's important to clarify that this is a temporary state and not the resting pulse pressure measurement.
