Final answer:
Variable annuities must be sold with a prospectus and a rider.
Step-by-step explanation:
Variable annuities must be sold with a prospectus and a rider. An annuity is a financial product that provides a stream of income in retirement. A prospectus is a document that contains important information about the investment, including fees, risks, and performance history. A rider is an additional provision that can be added to an annuity contract to customize its features, such as death benefits or inflation protection.
