Explanation:

This is a therapy in which someone is assisted by a therapist to overcome their fears or phobias.

A hierarchy of individual things that a person may fear are listed when they will assign their scale of fear for each from the least feared to the most feared .

Then in vitro which is being exposed to the image of that thing one fears is used and in Vivo where the person is exposed to the actual snake .
