One of the Primary Things That Differentiates the Termination Stage

One of the primary things that differentiates the termination stage from the maintenance and action stages is that:

A) there is an awareness that there is a problem in the termination stage.
B) it is only important to have stage-matched interventions in the termination stage.
C) in the termination stage, the new behaviour has become so automatic that it won't return.
D) the termination stage is thought to involve more energy and effort than the other two stages.
