7: When you phone one of your friends, she is cold and distant toward you.
  After hanging up, you consider the possible causes for her behavior.
  According to Kelley's covariation model of attribution, you would
  consider three kinds of information.  Which is NOT one of them?

 C: how other friends of yours have been acting toward you when you
    phone them

Incorrect.

In Kelley's model, how other friends have been acting toward you on the phone is consensus.  Consensus is whether others behave similarly in this situation.   Because this is part of Kelley's covariation model of attribution, it is incorrect as an answer to question 7.
