How do riders typically affect the premium of an insurance policy?

Riders are additional benefits or endorsements that can be added to an insurance policy to customize coverage. When riders are included, they enhance the features of the base policy, offering additional protection or options tailored to the insured's needs. This extra coverage typically comes at an additional cost, resulting in an increase in the overall premium of the policy.

For example, if a policyholder adds a rider that provides coverage for critical illness or accidental death, the added benefits essentially elevate the insurer's risk exposure. Insurers usually factor in this increased risk when calculating the premium, leading to higher charges for the policy. Thus, option C accurately captures the relationship between riders and premiums, highlighting that the inclusion of enhanced benefits generally leads to an increased cost for the policyholder.
