ODD is an abbreviation for :-

The correct answer is Option (4) → Oppositional Defiant Disorder

Option (1) Obsessive Deficit Disorder — Incorrect. There is no such disorder. ‘Obsessive’ belongs to obsessive-compulsive disorder, and ‘deficit’ to attention-deficit hyperactivity disorder.

Option (2) Obedience Defiant Disorder — Incorrect. There is no such disorder; the children in question are disobedient, not marked by obedience.

Option (3) Oppositional Deficit Disorder — Incorrect. There is no such disorder. The ‘D’ in the middle stands for defiant, not deficit.

Option (4) Oppositional Defiant Disorder — Correct. Placed under disruptive, impulse-control and conduct disorders, ODD is seen in children who display age-inappropriate amounts of stubbornness, are irritable, defiant, disobedient, and behave in a hostile manner. They do not see themselves as angry or defiant and justify their behaviour as a reaction to circumstances.
