The correct answer is A. The social construction of health
Step-by-step explanation:
The social construction of health is a study of sociology that focuses on analyzing and researching the way illnesses, medicines and concepts related to health can influence the construction of society including the way individual perceive health and illnesses and the influence this perception has. On the other hand, the Rating of Perceived Exertion (RPE) is a rate that measures the perception of individuals about the exertion or use of energy during activity. This means the RPE does not measures physical factors such as heart rate to determine the physical effort an activity requires but focuses on the individual's perception and because of this the RPE is often classified as an example of the social construction of health because both of them focus on the social aspects of health including the individual perception and its influence on health. Therefore, RPE is an example of the social construction of health.
