When I approach decisions and take action based on what is in the best interest of others,I am applying which ethical theory?

A) utilitarianism
B) altruism
C) virtue-based theory
D) ethical egoism

Altruism is an ethical theory that emphasizes selflessness and concern for the well-being of others. When making decisions and taking action based on what is in the best interest of others, this aligns with the principles of altruism. Utilitarianism, on the other hand, focuses on maximizing overall happiness or utility, while ethical egoism prioritizes self-interest above all else. Virtue-based theory emphasizes the development of personal virtues and morality. None of these theories directly align with prioritizing others' best interests, making altruism the best choice.
