What must the insurer do until the age stated in the contract for a noncancelable policy?

For a noncancelable policy, the insurer is obligated to renew the policy until the specified age in the contract. This means that regardless of changes in the insured's health status or any other factors, the insurer cannot refuse to renew the coverage as long as the policyholder continues to pay the premiums. This guarantees the policyholder continuous coverage without the risk of cancellation, which is a key feature of noncancelable policies designed to provide security and stability for the insured.

The other options do not align with the nature of a noncancelable policy. For instance, increasing premiums is not permissible under the terms of a noncancelable policy, as the premiums are typically locked in for the duration of the coverage. Redeeming claims is unrelated to the insurer's obligations regarding renewal and focuses on the claims process itself. Lastly, canceling the policy would contradict the fundamental premise of a noncancelable agreement, as it assures the policyholder of uninterrupted coverage. Therefore, the correct answer reflects the protection and commitment offered by a noncancelable policy.
