Step-by-step explanation:
The combination plan designed to protect an insured from an unpaid mortgage balance upon premature death is the Mortgage Protection Policy. This type of policy is specifically tailored to cover the outstanding mortgage debt in the event of the insured person's death. Unlike other types of life insurance such as Whole Life Insurance, Term Life Insurance, and Endowment Policy, which may provide death benefits that can be used for various purposes, the Mortgage Protection Policy focuses on safeguarding the insured person's mortgage.
