Final answer:
Level term life insurance is the type of policy that guarantees a level premium throughout the duration of the policy.
Step-by-step explanation:
The type of term life insurance policy that has its policy premium guaranteed to remain level throughout the term of the policy is called level term life insurance.
In level term life insurance, the premium stays the same for the entire duration of the policy, typically 10, 15, 20, or 30 years.
For example, if you purchase a 20-year level term life insurance policy with a premium of $500 per year, you will pay $500 every year for the entire 20-year term.
