Which nonforfeiture option gives the longest duration of coverage?

The reduced paid-up option is designed to extend coverage without requiring further premium payments. When a policyholder chooses this option, the cash value of the policy is used to purchase a reduced amount of paid-up life insurance. This means that while the coverage amount is less than the original policy, it remains in force indefinitely for the insured's life, as long as the policy has a cash value. Consequently, among the various nonforfeiture options, reduced paid-up insurance provides the longest duration of coverage.

In comparison, other choices such as cash surrender involve the policy's termination in exchange for a lump sum, which means no coverage continues. The extended term option allows for the policy's face amount to be converted into a term policy for a specified duration, but ultimately, this coverage will expire once the term ends. The automatic premium loan option allows for premiums to be paid using the policy's cash value but does not provide a long-term solution for coverage once the cash value is exhausted. Thus, the reduced paid-up option stands out for its ability to maintain coverage for a longer period.
