The Ad Guaranteed That You Would Be Skydiving After Only

The ad guaranteed that you would be skydiving after only a couple of hours of lessons.Megan was excited at the prospect.After enrolling in the class,she learned that rather than skydiving by herself,which is what the ad implied,she would be skydiving in tandem (belted to another experienced sky diver) due to safety requirements.Megan's disappointment was the result of:

A) Inadequate management of customer expectations
B) Under-promising and over-delivering
