Step-by-step explanation:
A- Your exercise regimen should always include rest and usually should gradually increase in intensity, therefor this is wrong.
B- You should not have extreme breaks in your workout schedule as your body will need time to readjust to working out again, so this is wrong
C- Exercise schedules should include time for breaks and specifically, for rest, this would be the correct answer in my opinion.
