Show Worked Solution

C is correct: Specific about physiological parameter, exercise protocol, and comparison groups.

Other Options:

A is incorrect: Too vague, lacking specific detail about exercise type and heart rate measurement.
B is incorrect: Too broad, covering multiple potential physiological responses without specificity.
D is incorrect: Asks “why” which is explanatory rather than investigative.
