Virginia Code § 38.2-3109 allows life insurance riders to extend coverage. A family term rider (option C) attaches to a primary policy (e.g., the breadwinner’s) and provides term insurance for all family members—spouse and children—under one supplement, often with a single premium. Option A (spouse term rider) covers only the spouse, not children. Option B (children’s term rider) insures only children, excluding the spouse. Option D (survivorship term rider) isn’t a standard term; “survivorship” typically refers to joint life policies paying at the second death, not family coverage. The study guide likely describes the family term rider as a cost-effective way to insure dependents, with examples showing level term benefits for each member, making C the accurate answer.
