What does integrity refer to?

Integrity refers to the quality of being morally upright, which encompasses attributes such as honesty, fairness, and adherence to ethical principles. When someone demonstrates integrity, they act consistently with their values and principles, regardless of the circumstances they face. This concept implies a strong alignment between one's actions and their moral beliefs, ensuring that they do the right thing, even when it may not be the easiest choice.

The other options, while they touch on important aspects of life, do not capture the essence of integrity. Financial success pertains to wealth and monetary achievement, relational stability focuses on the quality of relationships, and intellectual capability relates to cognitive skills and knowledge. None of these options convey the ethical foundation that integrity embodies. Thus, the term specifically tied to ethical conduct and moral uprightness makes it the correct choice.
