When Attempting to Explain Why a Consumer Purchases a Ford

When attempting to explain why a consumer purchases a Ford automobile instead of a Honda automobile or a Compaq computer instead of an IBM computer,an economist would assert:

A) that the consumer is making a decision based on what gives him maximum utility.
B) that everyone knows Hondas are superior to Fords; the consumer cannot possibly be maximizing his utility.
C) that everyone knows IBM computers are superior to Compaq computers; the consumer may be maximizing his utility at the margin,but is not maximizing total utility.
D) that there is no standard explanation for consumer choices because consumers have varied tastes and preferences.
E) that since rationality is bounded by lack of information,a consumer purchases goods based on convenience than on utility maximization.
