Which of the following is NOT a characteristic that all minerals must have?

The thing being tested is what defines a mineral in chemistry and geology. Minerals are inorganic, naturally occurring solids with a definite chemical composition. Being organic is not required and, in fact, would disqualify something from being a mineral, since organic compounds are carbon-based and typically associated with living systems, not formed by geological processes. That’s why inorganic fits as a required trait, and naturally occurring and definite chemical composition fit as essential traits as well. For contrast, an organic material like plant matter or fossilized remains isn’t considered a mineral because it lacks the inorganic chemistry and crystal-forming processes that minerals have.
