The correct order for administering basic life support (CPR) according to the American Heart Association's guidelines is d. Airway, breathing, circulation. This means that the first step is to ensure that the airway is clear, followed by providing breaths to the person in need, and then focusing on circulation by providing chest compressions. This order is based on the importance of ensuring that oxygen reaches the lungs and that blood continues to circulate throughout the body.
