Which of the following types of policies provides permanent protection at the lowest annual premium?

Term insurance provides coverage for a specific period, typically ranging from 10 to 30 years, and does not offer permanent protection. While it may have lower premiums than Whole Life in the short term, it lacks the cash value component and expires once the term ends, resulting in no coverage beyond that point.

Endowment policies are designed to pay a benefit either upon death or after a specified period, making them more expensive due to their dual function. They typically have higher premiums than Whole Life policies, as they are intended to provide a lump sum at a predetermined time, which is not necessary for permanent protection.

Limited-Pay Life insurance requires premiums to be paid for a limited number of years while still providing permanent coverage. However, the annual premiums for Limited-Pay Life are often higher than for Whole Life policies, as the payments are concentrated over a shorter duration, leading to a higher cost per year.
