Explanation / Answer

Schizophrenia has positive as well as negative symptoms. Positive symptoms include the symptoms that a person did not have before they were diagnosed as schizophrenic. Negative symptoms are characterized by decline in something that a person could carry out before being diagnosed. Avolition is feeling lethargic or decline in motivation. A person before being diagnosed with schizophrenia had high motivation, however, the mental disorder led to them feeling less motivated.

Thus, the correct answer is option, D.
