Answer: B

Explanation:

The portion of the premium applied to purchase pure insurance is known as the mortality cost.

The mortality cost refers to the portion of the insurance premium that is allocated specifically for the risk of death, which is the fundamental purpose of life insurance. This cost reflects the insurer's assessment of the likelihood of a claim being made based on the insured's mortality risk.

A) Cash value

Cash value is a component of certain types of life insurance policies, typically whole life, that accumulates over time and can be borrowed against or withdrawn. It does not pertain to the portion of the premium used for pure insurance coverage, making it an incorrect choice.

B) Mortality cost

Mortality cost is the correct answer as it specifically denotes the part of the premium that is used to cover the risk of death, thus directly relating to the fundamental nature of insurance coverage. This cost is essential to understanding how premiums are structured in relation to the risk being insured.

C) Loading charge

The loading charge covers the administrative costs and profits of the insurance company. While it is part of the total premium, it does not contribute to the actual risk coverage, which is why it is not the correct answer.

D) Net premium

Net premium is the portion of the premium that remains after deducting the loading charge and represents the risk portion of the premium. However, it is not specifically defined as the mortality cost, hence it cannot be considered the correct answer.

Conclusion

The mortality cost is definitively the portion of the premium that directly relates to the risk of death, making it the correct choice. Other options, while related to insurance premiums, either refer to different components or do not specifically address the pure insurance aspect, thus failing to answer the question accurately.
