A Clinician Obtains Information Regarding a Child's Problem Behaviours from Both

A clinician obtains information regarding a child's problem behaviours from both her father and her teacher. However, the reports differ significantly. The likely reason the reports are inconsistent is because

A) Teachers spend less time with children than do their parents
B) Teachers and parents see the problem behaviours from different perspectives
C) Fathers tend to lie about problem behaviours more than teachers
D) Teachers tend to lie about problem behaviours more than parents
