Final answer:
To override a habit, one must change the routine, which is the behavior itself, while maintaining the same cues and rewards.
Step-by-step explanation:
The part of a habit that requires change if you want to override it is B) Routine. Habits are made up of three core components: a cue, a routine, and a reward. The cue triggers the behavior, the routine is the behavior itself, and the reward is what reinforces the behavior. To change a habit, you need to keep the cue and reward the same while changing the routine. This is because the routine is the actual habitual action that you perform, so altering it is essential to break the old habit and form a new one. For instance, if you have a habit of snacking on sweets when you're stressed (cue), you can try going for a quick walk (new routine) to help you cope, so the satisfaction you feel afterwards (reward) reinforces the new behavior.
To override a habit, you need to change the routine associated with the habit. The routine is the specific behavior or action that you engage in when the habit is triggered by a cue. By changing the routine, you can break the habit loop and form a new habit. The reward, which is the gratification or positive outcome that comes from the habit, remains constant.
