Answer :
The correct answer is:
C. Opponents who hold grudges make better competitors.
Explanation:
1. A. Opponents in any game are not enemies: This is true. In games or sports, opponents are simply individuals or teams you compete against, but they are not necessarily your enemies outside of the competition context.
2. B. Opponents in sports are temporary challengers: This is true. Opponents in sports or games are temporary challengers because the competition is specific to the game or event being played, and they are not consistently against you in all aspects of life.
3. C. Opponents who hold grudges make better competitors: This statement is incorrect. Holding grudges can negatively impact a competitor's performance and mindset. It can lead to distractions, emotional responses that affect decision-making, and an unhealthy focus on the past rather than the present competition.
4. D. Opponents who keep grudges are engaged in an unhealthy behavior: This is true. Holding grudges is generally considered unhealthy behavior, as it can create negative emotions, hinder personal growth, and impact relationships, including those in competitive settings.
Therefore, the correct choice is C, as opponents who hold grudges do not make better competitors due to the negative effects grudges can have on performance and sportsmanship.
