Participants in one study wore digital audio recorders. Research assistants coded the sounds and compared the coded behaviors to the participants' self-reports of behavior. Friends of the participants also made ratings of behavior frequencies. The findings show that:

A. friends were most accurate at predicting participant behaviors.
B. for some behaviors, the participants were more accurate and for other behaviors, friends were more accurate.
C. there was not a relationship between the participants' self-reports and their behaviors.
D. participants were most accurate at predicting their own behaviors.
