What does 'probity' refer to?

The term 'probity' is derived from Latin and refers to having complete integrity and adherence to moral and ethical principles. It embodies the idea of honesty and uprightness in character and conduct. When someone is described as having probity, it signifies that they are trustworthy and honest in their dealings, acting with a strong sense of what is right and just. This quality is often prized in various contexts, such as in business, law, and personal relationships, where trustworthiness is vital.

In contrast, the other options present concepts that do not relate to integrity. For instance, intense beauty refers to aesthetic appeal, a state of extreme poverty has no connection to moral values, and the art of persuasion focuses on the ability to influence others rather than embodying ethical principles. Thus, 'complete integrity' best captures the essence of probity.
