Answer:
a. biological, psychological and social factors contribute equally to most disorders
Step-by-step explanation:
Abnormal models are hypotheses and theories that psychologists, psychiatrists, and other practitioners who are involved in the ram of psychology use to explain psychological abnormalities that can affect humans.
The multipath abnormality model is a branch of this approach that asserts that biological, psychological, and social factors contribute equally to most psychological disorders. This kind of model therefore excludes the hypothesis that the psychological disturbances are caused by only one factor.
