What does the term rectitude refer to?

The term rectitude refers specifically to moral integrity and the quality of being upright or honest in one's actions and decisions. When someone possesses rectitude, it indicates that they adhere firmly to ethical principles and demonstrate honorable behavior. This understanding of rectitude encompasses virtues such as fairness, honesty, and a steadfast commitment to doing what is right.

In the context of the other choices, the definitions do not align with the meaning of rectitude. For example, a lack of integrity or being selfish would directly contradict the notion of moral uprightness. A state of confusion or disorder also stands in stark contrast to the clarity and order associated with having good moral character. Thus, the choice highlighting uprightness resulting from being honorable and honest accurately captures the essence of what rectitude signifies.
