Which AWS service should the company use to meet these requirements?

Explanations:

Amazon Route 53 is a scalable domain name system (DNS) service that helps route traffic globally. While it can improve availability and provide routing policies, it does not directly accelerate content delivery or reduce latency for a global audience.

Amazon CloudFront is a content delivery network (CDN) that caches content at edge locations around the world. This service reduces latency by serving content closer to users, ensuring faster delivery of website assets to a global audience.

Elastic Load Balancing (ELB) distributes incoming application traffic across multiple targets, such as EC2 instances. While it improves fault tolerance and can manage traffic effectively within a specific region, it does not specifically address global reach or latency reduction for a worldwide audience.

AWS Lambda is a serverless compute service that runs code in response to events and automatically manages the computing resources required. Although it can be part of a solution that scales applications, it does not inherently improve global content delivery or reduce latency for users accessing a website.
