Which of the following is true regarding the factors affecting premium determination?

The statement that includes sex and payment guarantee loading is accurate because these factors significantly influence the computation of life insurance premiums.

In life insurance underwriting, sex is a critical factor as statistical data often shows variances in life expectancy between genders, influencing risk assessments. This means that insurers may charge different premiums for males and females based on life expectancy data.

Payment guarantee loading refers to the additional amount that may be added to the premium to ensure that benefits can be paid over a specified period, regardless of the claimant’s lifespan. This guarantees the insurer can meet its commitments and manages risk effectively.

By incorporating these variables, insurance companies can align premiums more closely with the risk they are assuming when insuring an individual. This results in more personalized, equitable premium pricing for the insured while also maintaining the insurer's financial stability. The other options do not comprehensively capture the range of factors that influence premium determination, making the selected answer the most accurate representation of the complexity involved.
