Which of the following is NOT a common life insurance nonforfeiture option?

Life insurance nonforfeiture options are provisions that ensure policyholders receive some benefit or value from their policy if they stop paying premiums. The common nonforfeiture options include reduced paid-up insurance, cash surrender value, and extended term insurance. These options allow a policyholder to access a portion of their policy's value or to continue coverage in a different form without having to pay additional premiums.

A life income annuity is not classified as a nonforfeiture option. Instead, it is a financial product that provides guaranteed income for a specified period or for the lifetime of the annuitant. While it may relate to the broader topic of life insurance and can be a result of converting policy value, it does not fall under the typical nonforfeiture options defined in life insurance contracts. Thus, it stands out as the correct choice among those listed, as it does not serve the same purpose of ensuring access to policy value after premium payments have ceased.
