Answer:
This preference best illustrates the importance of the Mere Exposure Effect.
Step-by-step explanation:
The Mere Exposure Effect is a psychological phenomenon in which an individual tends to prefer certain things such as products or brands only because he/she is familiar with them.
It is also known as the Familiarity Principle and it centers on the idea that the mere exposure to a particular stimulus will increase an individual's likeness of it.
In this case, shoppers tend to prefer certain products because they are familiar with the brand names; they were merely exposed to these names and increased their liking of it as such.
