The correct answer is A. The rational decision-making perspective
Step-by-step explanation:
In economy and psychologist, the rational decision-making perspective occurs when an individual uses logic and reason to buy a product which includes comparing prices, studying brands and getting information about which product is better. This differs from the experiential perspective because in this the customer buys a product based on previous experiences and from the affect-based perspective because in this the emotions and feelings help a customer to buy a product. In the case of Greg, his decision mainly shows the rational decision-making perspective because he acts based on logic and reasoning and because of this, he looks for information in multiple sources and compares different trucks before buying one.
