Answer:
A) Social Withdrawal
Step-by-step explanation:
"Schizophrenia" can be classified into two types: Type 1 (positive symptoms) and Type 2 (negative symptoms). The positive symptoms refer to those behavior which the person is experiencing now but hasn't experienced before having the schizophrenia. The negative symptoms refer to those behavior which the person suddenly removed from his life but he has been experiencing before having schizophrenia.
Choices B, C and D are positive symptoms, therefore, they belong to Type 1 Schizophrenia. Choice A (Social Withdrawal) is a negative symptom, therefore, it belongs to Type 2 Schizophrenia. This means that the person is no longer interested in interacting with other people just as he used to before having the disorder.
