Final answer:
The correct option is to perform the exercises twice daily, 10 reps for each exercise.
Step-by-step explanation:
HEP b.i.d. stands for Home Exercise Program, which should be performed twice daily, 10 reps for each exercise. So, option b is the correct one. Performing exercises once daily with 5 reps for each exercise (option a) or every other day with 15 reps for each exercise (option c) would not meet the prescribed instructions. It is important to follow the prescribed frequency and number of reps to ensure that the exercises are performed as intended.
