B: how your friend acted toward you the last few times you called
Incorrect.
How your friend has acted toward you the last few times you called
would be whether your friend is consistent. Consistency in Kelly's model
is: Does this person usually behave this way in this situation (usually cold
and distant on the phone towards you). Since this is part of Kelley's
covaration model of attribution, it is incorrect as an answer to question 7.
