Answer:
A positive symptom of schizophrenia would be laughing about at inappropriate things (option C).
Explanation:
Schizophrenia is a psychiatric condition characterized by a dissociation from reality and antisocial behavior. This mental disorder produces inappropriate behavior and thinking, since the patient lives in a world of fantasy, delirium or hallucinations.
Actions such as laughing at inappropriate things, talking to oneself, or showing behavior that is not in line with reality are symptoms that can be observed in schizophrenia.
The other options are normal behaviors that do not correspond to mental conditions such as schizophrenia.
