Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → B and C only
(A) Abnormal behaviour is behaviour that is deviant, distressing, dysfunctional and delusional. — Incorrect. The four Ds of abnormal behaviour are deviant, distressing, dysfunctional and dangerous. Here 'delusional' has replaced 'dangerous'; delusions are a symptom of some disorders.
(B) Behaviours that represent a deviation from social norms are seen as abnormal. — Correct. Behaviour is seen as abnormal when it represents a deviation from social norms, that is, when it goes against what society expects.
(C) Behaviours that interfere with optimal functioning and growth are seen as abnormal. — Correct. Behaviour that interferes with optimal functioning and growth is also seen as abnormal, because it stops the person from living and developing well.
(D) Psychological disorders have been classified by the WHO in DSM-5 and by the American Psychiatric Association in ICD-10. — Incorrect. The two systems are swapped. The WHO prepared ICD-10, and the American Psychiatric Association prepared DSM-5.
