Which cloud computing benefit enables a company to deliver applications to users worldwide using AWS Regions, Availability Zones, and edge locations?

Global reach is the correct answer because AWS's expansive global infrastructure, including Regions, Availability Zones, and edge locations, is specifically designed to deploy applications closer to users worldwide, minimizing latency and improving performance. Economy of scale refers to the cost savings achieved by a large-scale provider like AWS, not the ability to deploy globally. Agility describes the speed and flexibility of provisioning resources, which is a benefit of cloud computing but doesn't directly address worldwide delivery. High availability ensures an application remains operational even if components fail, but it's a characteristic of a well-architected system within a region, not the primary benefit for global user distribution.
