i think it's d, but am not sure.

Correct answer choice is:

D. Three to five.

Explanation:

Depending on the consistency level of the person, exercises may differ. For instance, a freshman will concentrate on an exercise that will begin off at a moderately light level of endeavor. By improvement, the freshman will ultimately work towards a speed that produces a reasonable level of endeavor. These exercises can be performed 3-5 times a week for 15-25 minutes.
