Answer:
The correct answer is letter "C": Is the customer's decision based on a new or a regular purchase?
Explanation:
Consumers might have trouble while purchasing articles they usually do not. Some of them take the time to make a research before they go to a store to have an idea of what type of product might satisfy their needs based on functionality, quality, and price.
However, even if counting with that information, consumers might find other special deals in the same store which makes them doubt. If a sales representative questions himself "Is the customer's decision based on a new or a regular purchase?", at the moment of approaching the client the clerk will know how to reach the consumer attempting to close a sale.
