Why Is a Typical Person Likely to Gather More Information

Why is a typical person likely to gather more information when buying a new car than when voting for a Member of Parliament?

A) because a person's preferences are more likely to be met with little effort in the political sphere but this is not the case when buying a car in the private marketplace
B) because it is less costly to acquire information about consumer items than it is about political candidates
C) because buying a new car affects a person more immediately and personally compared to voting for a Member of Parliament; in the latter, a person's vote is only one of many voters and therefore, not likely to have a large impact on the outcome
D) because the effects of buying a car are long term while a Member of Parliament has a relatively short tenure
