We can be most certain that their ratings represent private conformity rather than public conformity if
a. they exhibit much less conformity in the presence of the experimenter.
b. they give the same ratings alone as they do in the group.
c. their ratings result from their desire to fit in with the rest of the group members.
d. they are not especially motivated to be accurate in their judgments.
