Step-by-step explanation:
The answer to the student's question is a. Talk test. This method refers to a subjective measure of exercise intensity where an individual is able to talk but not sing during moderate-intensity aerobic activity. During vigorous-intensity activity, the person would not be able to say more than a few words without pausing for breath. The talk test serves as a practical way to assess respiratory and cardiovascular demand during exercise without the need for specialized equipment.
Symptoms such as shortness of breath, wheezes, or hoarseness might be assessed using this test, as it can provide important clues about a person's respiratory health. Unlike the self-report inventory, which is an objective measure usually relating to psychological assessments, the talk test is more informal and based on the participant's own perception of effort and ability to speak.
