Explanation

Important note: The provided correct answer (C - Guideline) appears to conflict with standard business rules classification. Based on the wording, B. Constraint is the more defensible answer, and you should verify this against your course materials.

"Vehicle usage MUST NOT BE Commercial" uses mandatory prohibition language ("MUST NOT"), which is the defining characteristic of a Constraint - a hard rule that restricts behavior with no discretion allowed. Constraints enforce boundaries; they don't merely suggest them.

• A. Calculation is wrong because there is no formula, algorithm, or derived value here - nothing is being computed.
• C. Guideline is wrong (despite being listed as correct) because guidelines use softer language like "should not" or "is recommended." "MUST NOT" leaves no room for judgment or flexibility, which disqualifies it as a guideline.
• D. Inference is wrong because an inference derives a new conclusion from existing facts (e.g., "IF X THEN Y"). This rule doesn't derive anything - it prohibits something outright.

Memory tip: Map the modal verb to the rule type - MUST/MUST NOT = Constraint, SHOULD/SHOULD NOT = Guideline. If your exam source genuinely marks this as a Guideline, ask your instructor to clarify the classification framework being used, as it would be non-standard.
