Which of the following is a type of permanent life insurance?

Whole life insurance is considered a type of permanent life insurance because it provides coverage for the entirety of the insured's life, as long as premiums are paid. Unlike term life insurance, which only offers coverage for a specific period, whole life insurance has a cash value component that grows over time and can be accessed by the policyholder. This permanent feature distinguishes it from temporary life insurance products.

The other options listed are forms of life insurance but do not qualify as permanent insurance. Term life insurance provides protection for a set number of years and does not accumulate cash value, while accidental death insurance covers only death due to accidents, and annual renewable term insurance is a type of term insurance that can be renewed annually but does not provide lifelong coverage or a cash value.
