Which of the following insurance options allows the policyholder to increase the death benefit in the future?

The option that allows the policyholder to increase the death benefit in the future is the guaranteed insurability option. This feature is particularly valuable as it allows policyholders to increase their coverage without having to undergo further medical underwriting, typically at specified times or after certain life events, such as marriage or the birth of a child. This flexibility is essential for policyholders who anticipate changes in their financial responsibilities over time.

The other options do not focus on increasing the death benefit. The accelerated benefit rider provides access to a portion of the death benefit while the insured is still alive, usually due to a terminal illness. The waiver of premium rider allows the policyholder to stop paying premiums if they become disabled but does not affect the death benefit amount. The accidental death benefit offers an additional amount if the insured's death occurs due to an accident, but it does not allow for an increase in the base death benefit over time.
