Answer:
E. Learning
Explanation:
Consumer behaviour is dictated by learning. Learning can be defined as a behavioural change after interacting with one's environment. Our preferences, tastes, values, and attitudes are acquired through learning. For example if one touches a hot object, he will learn that hot objects cause pain and he will avoid it in future.
In this instance Alice buys FitJoy snack bars that used to satisfy her. Now the snack bars don't satisfy her anymore, so she learns to stop buying and looks for another alternative.
