Which of the following is NOT a type of policy for mortality risk?

Mortality risk relates to the financial consequences of an insured's death, and different types of insurance policies address this risk in various ways. The key types of policies—like term assurance, endowment assurance, and whole of life assurance—are specifically crafted to provide a payout upon the death of the insured within certain terms.

Term assurance provides coverage for a specified period, paying out if the insured dies during that term. Endowment assurance combines life coverage with a savings component, paying out either upon death or if the insured survives to the end of the policy term. Whole of life assurance offers lifelong coverage, ensuring a payout at death whenever that occurs.

In contrast, accidental death cover is not a type of policy specifically designed to cover mortality risks associated with the natural life span. Instead, it provides benefits only in cases where death results from an accident, excluding other causes of death. This limitation means it doesn't fit within the general types of life insurance policies used to manage broader mortality risks.
