Strength cannot be won by war or hatred, as these are destructive and negative forces that do not lead to true strength. Instead, strength can be won through love and positive actions. Here is a detailed explanation of why option 'C' is the correct answer:

1. Overview:
Strength is not merely physical power or dominance over others. True strength lies in one's character, resilience, and ability to overcome challenges. It is a quality that enables individuals to face adversity with courage, determination, and compassion. Strength is not gained through acts of aggression or hatred, but rather through acts of love, kindness, and understanding.

2. Strength through Love:
- Love is a powerful force that can inspire individuals to act selflessly for the well-being of others. When we act out of love, we cultivate empathy, compassion, and a sense of unity with those around us.
- Love encourages cooperation, collaboration, and the building of positive relationships, which in turn strengthen individuals and communities.

3. Key Points about Love:
- Love promotes resilience and inner strength: When we love ourselves and others, we develop a strong sense of self-worth and emotional stability. This enables us to face challenges with greater resilience and bounce back from setbacks.
- Love fosters positive emotions: Acts of love, kindness, and gratitude trigger the release of chemicals in the brain that promote feelings of happiness, contentment, and well-being. These positive emotions contribute to our overall strength and ability to face difficulties.
- Love promotes personal growth: When we act with love, we are more open to learning, personal growth, and self-improvement. We are willing to acknowledge our mistakes, apologize, and seek forgiveness, which strengthens our character and relationships.

4. Strength through Positive Actions:
- Strength can also be won through positive actions such as perseverance, determination, and self-discipline. When we set goals, work hard, and overcome obstacles, we develop a sense of achievement and personal growth.
- Positive actions also include acts of service, generosity, and helping others. These selfless actions not only benefit those in need but also contribute to our own sense of purpose, fulfillment, and strength.

5. Conclusion:
True strength is not obtained through war or hatred, but rather through love, compassion, and positive actions. By cultivating love within ourselves and expressing it through our behavior, we can build resilience, character, and inner strength. This strength enables us to overcome challenges, build positive relationships, and make a positive impact on the world around us.
