Which cloud computing benefit ensures users have continuous access to a cloud-based application with minimal downtime?

High availability is the correct answer because it refers to the ability of a system to remain operational and accessible for a high percentage of the time, minimizing downtime. This is achieved through redundant components and failover mechanisms, ensuring continuous access to applications even if a component fails. Agility refers to the ability to rapidly develop, test, and deploy applications, which doesn't directly address continuous access. Scalability is the ability to increase or decrease resources to handle changes in demand, but it doesn't guarantee continuous operation during failures. Elasticity is a specific type of scalability that automatically adjusts resources based on demand, but like general scalability, it doesn't inherently ensure continuous access in the face of outages.
