A premise in an argument is a statement that serves as evidence or support for the conclusion. It is essential for a premise to be true in order for the argument to be valid. Therefore, one key characteristic of a premise is that it must be able to be true. If a premise cannot be true, then it fails to provide a solid foundation for the argument. This is why the correct answer is C.

Option A, "Not Necessarily False," is not a key characteristic of a premise because a premise ideally should be true rather than just not necessarily false. Option B, "Logical Opposition," is not a key characteristic of a premise but rather a concept related to the relationship between statements. Option D, "What is a premise?" is not a characteristic of a premise but a question seeking clarification on the term.
