• A. Routine
• B. Custom
• C. Habit
• D. Ritual

Answer: (C)

Habit is a regular behavior that becomes automatic and resistant to change. When you repeat an action in a consistent context, your brain starts to link the cue (like a time of day or an environment) with the action and its reward, so the behavior can occur with little conscious thought. That automatic loop makes it hard to give up or modify, even when you know you should. For example, reaching for a snack whenever you sit down to watch TV can become a habit you perform without planning.

A routine, by contrast, is a planned sequence of actions you follow regularly and can adjust or skip if you want. A custom is a shared social practice or norm within a group, not necessarily automatic for an individual. A ritual is a formal, symbolic sequence of actions often tied to tradition or meaning, rather than a personal, automatic behavior.
