What does it mean if something is legal but not wise?

If something is described as legal but not wise, it implies that although the action or decision adheres to the law and does not violate any legal statutes, it may still have negative outcomes or be harmful in practice. This distinction is crucial because just because something is permissible under the law doesn't mean it should be pursued. For instance, a legal action such as using certain substances may be permissible in some contexts, but it might not be advisable due to potential health risks or social consequences. Thus, option A accurately captures the essence of this concept by emphasizing that legality does not guarantee wisdom or sound judgment in decision-making.
