If an insurance company makes an income payment to an annuitant during the first payment period after the purchase, the contract is best described as:

A deferred annuity involves a waiting period between the purchase of the contract and the commencement of income payments. During this deferral period, the funds within the annuity grow tax-deferred, allowing for potential accumulation before annuitization and payout.

A variable annuity offers investment options within the contract, allowing the annuitant to select from various subaccounts that are tied to the performance of underlying investments such as stocks and bonds. The income payments from a variable annuity are not fixed and fluctuate based on the investment performance.

A fixed annuity guarantees a set amount of income payments to the annuitant, usually based on a predetermined interest rate or a fixed schedule. These payments remain consistent throughout the payout phase, providing a stable income stream for the annuitant.
