Abnormal behavior can be defined as which of the following? (select all that apply.)
-it is the inability to appreciate the wrongfulness of one's acts.
-it is insanity.
-it manifests itself as affecting the way that a person thinks, behaves, and interacts with others.
-it is a mental illness.

It manifests itself as affecting the way that a person thinks, behaves, and interact with others

Explanation:

The inability to appreciate the wrongfulness of one's acts is the legal way to define insanity. Insanity and abnormal behavior are two different things. Insanity is a mental disorder over a long period of time and abnormal behavior is not a mental illness. Instead a mental illness or insanity can only make people exhibit some behaviors that are abnormal. Hence the reason for my choice of answer.
