Which of the following best describes "tacit" understanding?

The term "tacit" refers to something that is understood or implied without being explicitly stated. A tacit understanding often exists between people who share common knowledge or experiences, allowing them to comprehend something without needing to verbalize it. This kind of understanding can be found in professional settings, social interactions, and cultural contexts where shared backgrounds contribute to a mutual grasp of certain concepts or expectations.

Other options, such as those describing a situation that is openly expressed, written in detail, or clear and defined, do not capture the essence of "tacit." These terms suggest a level of articulation and clarity that is absent in tacit forms of understanding, which thrive in subtleties and unspoken agreements. Thus, the correct description aligns perfectly with the meaning of tacit, highlighting its nature as something understood rather than stated explicitly.
