D: how you acted toward your friend during the phone call
Be careful here. Clearly, our own behavior does
influence how others interact with us, but the question asks specifically
about Kelley's covariation model of attribution. Always be sure you
are answering the question, and that your answers meet the conditions specified
in the question. The question was not a more general question asking
about influences on social interaction. Since this is not part of
Kelley's covariation model of attribution, it is correct as an answer to
question 7.
