Final answer:
The most suitable life insurance policy for N, who wants permanent protection with level premiums that are paid up by retirement, is the 30 Pay Life insurance policy.
Step-by-step explanation:
N is looking for a life insurance policy that will provide permanent protection with level premiums and will be fully paid up by the time he retires at age 70. The best option for N is a 30 30-pay life insurance policy. This type of policy allows N to pay a fixed premium for 30 years, ensuring that the policy is fully paid by his retirement age, and it will continue to provide coverage thereafter without additional payments.
Term to Age 70 is not suitable because it only provides coverage until N reaches 70, at which point coverage would end. Universal Life and Adjustable Life policies could provide permanent protection, but the premiums may not be level, and the policy may not necessarily be paid up by the time N retires.
Life insurance choices heavily depend on an individual's financial goals, current age, desired retirement age, and the structure of insurance products available.
