The correct answer is "It is an annuity based business." An annuity is a financial product that provides a fixed sum of money at regular intervals, typically annually. In the context of a business, an annuity-based business refers to a business model where the company earns a steady stream of income from existing customers or clients over an extended period of time, without relying on generating new revenue. This could be through long-term contracts, subscription-based services, or recurring payments. Therefore, the business can continue operating for several years without needing to generate any new revenue because it already has a reliable source of income from its existing customer base.
