Answer: The correct answer is "d) In order to maximize utility, Ellie should buy more of Alpha and less of Beta".
Explanation: This indicates that in order to maximize utility, Ellie should buy more of Alpha and less of Beta, because the alpha product gives Ellie a greater utility than the beta product, so since each product is worth $ 1, to maximize its utility Ellie should buy as many Alpha products as she want until the utility she get by buying one more of these is less than the utility she would get from buying a Beta product.
