In LSAT questions, it is crucial to pay attention to specific language cues that indicate the relationship between the elements being discussed. In this question, the word "must" is the correct choice because it straightforwardly signifies a mandatory condition. When paired with "Answer," the word "must" indicates a requirement or necessity, emphasizing that the condition is non-negotiable. This precision in language is a common feature of LSAT questions, making the use of "must" in this context the most appropriate choice.

Options A, C, and D are incorrect as they do not convey the same level of necessity and obligation as the word "must" does. They either introduce exceptions (A - Except), imply a more general requirement (C - Necessary), or focus on the absence of something (D - Without), none of which explicitly emphasize the mandatory nature of the condition as clearly as "must" does in this context.
