Abstract standards that provide a person with their own code of conduct are:

A. Beliefs are convictions that something is true, often without requiring proof, but they do not necessarily form a personal code of conduct. B. Values are correct because they are abstract standards that guide behavior, decision-making, and provide a personal code of conduct. C. Personal philosophy is a broader worldview or life perspective, not specifically a code of conduct. D. Attitudes are emotional feelings or mental positions toward people, objects, or situations, but they are not the same as values.
