Charlotte and Craig Are Both Participating in a Psychology Experiment

Charlotte and Craig are both participating in a psychology experiment and are sitting in a small room filling out some personality questionnaires. Little does she know, but Craig is a confederate of the experimenter and is displaying behaviours that are similar to her own (e.g., he shakes his leg too, he bites his lip, etc) . Craig accidentally drops his pencil case and spills pens all over the floor. According to principles of the chameleon effect, Charlotte would most likely

A) drop her own pencil case so that Craig doesn't feel so bad.
B) laugh at Craig and smile at him but continue completing her questionnaires.
C) get out of her seat and help Craig pick up the dropped pens.
D) ignore Craig and continue completing her questionnaires.
