C is correct. Hawaiʻi regulates the use and retention of life insurance illustrations because illustrations can materially influence a consumer's understanding of premiums, policy values, guarantees, dividends, and non-guaranteed elements.

Under HRS §431:10D-407, a copy of the applicable basic illustration , any revised illustration, and specified certifications must generally be retained by the insurer until three years after the policy is no longer in force . If no policy is ultimately issued, the statutory provision does not require a copy to be retained under this particular rule.

The requirement is substantially longer than simply retaining documentation for three years after issue. A policy could remain active for decades; under the statutory rule, the retention period extends throughout that active duration and then continues for another three years after termination.

Illustration rules are consumer-protection and market-conduct requirements. Producers and insurers must avoid presenting non-guaranteed values as guarantees or otherwise using illustrations in a deceptive manner. Hawaiʻi further treats violations of the illustration requirements as unfair or deceptive insurance practices.
