Answer:
oppositional defiant disorder
Explanation:
Oppositional defiant disorder refers to a disorder in which a teenager exhibits a persistent pattern of angry or irritable attitude, aggressive or argumentative actions, and vindictiveness towards those in authority. The child's conduct also disrupts the child's usual day-to-day routines, including family and school events. What makes this disorder different from usual oppositional attitude is how serious it is and how long it has been going on. As per the question, the unmanageable behavior of the child reflects oppositional defiant disorder.
