(a) false.
(b) true.

(B) True.

Explanation:

For sociologists, there are dominant norms that regulate society's well being and any behavior contrary to these will mean a person is perfoming deviant behavior.

Often psychologists will research on genetic causes, and of course other inner motivations. While in contrast sociologists will explain deviance focusing on how social boundaries, forces, and structures pose conditions where deviances takes place.

Thus psychological explanations take a different focus, they see individuals as unique and primary unit of analysis. They believe human beings are ultimately reponsible in cases of crimes or other acts that are deviant.

The personality of  an individual creates conditions for causing this deviances. Of course in some cases mental health issuses or non mental health concerns will link.
