The Insurance Commissioner may issue a(n) __________ to ensure compliance with an insurance law.

The correct answer is "Order" because the Insurance Commissioner has the authority to issue orders as a method to enforce compliance with state insurance laws and regulations. An order is a formal directive issued by the Insurance Commissioner that can require individuals or insurance companies to take specific actions to align with legal requirements. This can include anything from mandating corrective measures to imposing penalties for non-compliance.

On the other hand, regulations are established rules or standards created by the Commissioner that guide how laws are implemented but do not signify a direct enforcement action. A directive is generally more of an internal guidance tool rather than a formal enforcement mechanism, and a mandate typically refers to an authoritative command but is not commonly used in this specific context related to insurance law compliance by the Commissioner.
