Which word refers to the ability to make sensible decisions?

The term that refers to the ability to make sensible decisions is "discretion." Discretion involves the capacity to exercise judgment based on the information available and the context of a situation. It is a crucial skill in many areas of life, including personal decision-making and professional settings, where one must assess options carefully and choose actions that are appropriate and effective. Exercising discretion reflects an understanding of the nuances involved in decision-making, showing a level of wisdom and thoughtfulness.

The other terms do not pertain to decision-making: "disinterest" refers to a lack of bias or personal involvement, "dissolve" means to mix a substance with a liquid until it forms a solution, and "disparage" means to speak about someone or something in a way that shows strong disapproval and lack of respect. Each of these words relates to different concepts and does not capture the essence of sensible decision-making.
