A teacher can identify a stressed child when the child shows the following behavior:

Correct option is D

The correct answer is Aggressive behaviour.
Aggressive behavior is reactionary and impulsive behavior that often results in breaking household rules or the law; aggressive behavior is violent and unpredictable. According to research, a stressed student believes that by showing aggression in the class, he/she can overcome the stress causing factor. This academic stress is often marked with abrupt changes in personal style or violent outbursts. Here, a good thing for the teacher to do is to consult the case with the colleagues, principal or counsellors for suggestions to help the student. Approaching the student with a concerned attitude can also make an instant impact on the behaviour or performance of the student.
