A. Symptoms (mostly positive) of schizophrenia are related to excess dopamins in the brain

Explanation:

The dopamine hypothesis is of the premise that when there is hyper activity of dopamine in the limbic brain area, it contributes to the positive symptoms that can be seen in those that have schizophrenia. This hypothesis is due to the fact that dopamine has been seen as a neuro transmitter in the human brain. In simple terms it means that the unusual behaviour that people with schizophrenia have is due to the changes in their dopamine function.
