The Best Reason Why the Majority of Patient Samples Are

The best reason why the majority of patient samples are drawn in the early morning hours is because:

A) the patient will not be in the basal state early in the morning because this requires several hours of normal physical activity by the patient.
B) patients should have consumed a meal no less than three hours prior to the time of collection.
C) the patient will be in the basal state, having restrained from strenuous exercise and having fasted for approximately 12 hours.
D) patients are generally more agreeable with collection times scheduled early in the morning.
