Use the Accentuation Principle to Solve This: Suppose That John

Use the accentuation principle to solve this: Suppose that John thinks that people's weight is an important human attribute, and he categorises people as either 'fat' or 'slim'. Consequently:

A) slim people who weigh a bit more than other people in the slim category will be judged by John as slimmer than they really are.
B) fat people who weigh a bit more than other people in the fat category will be judged by John as fatter than they really are.
C) slim people will appear even slimmer when there are fat people near them.
D) John is more likely to recall people who are really fat or really slim.
