Final answer:
The best and most inexpensive insurance option for clients needing to cover a mortgage in case of death is Term life insurance, as it provides a death benefit without the additional cost of a cash value component.
Step-by-step explanation:
Clients who wish to ensure they have enough insurance to pay off their mortgage in the event of one of their deaths, while seeking the most inexpensive option, should consider A. Term life insurance. This type of insurance is designed for a specific period, or term, and usually has lower premiums than other types of life insurance. Unlike whole life insurance, term life does not carry a cash value and simply provides a death benefit if the insured individual dies within the term period. Whole, universal, and variable life insurance policies include investment components, which tend to make them more expensive as they offer both a death benefit and a cash value component that grows over time.
