Answer:
The answer is option (B) gamification.
Step-by-step explanation:
Gamification is a term that describes when game principles and game-design elements are applied to non-gaming settings or activities that are not games.
The goal or purpose of gamification is to promote productive engagements and healthy competition as the addicting and fun elements of games are applied to real-world activities.
