Route 53 is the AWS DNS service responsible for domain name resolution and management. It offers highly reliable and scalable domain registration and DNS routing solutions. Route 53 allows users to connect user requests to infrastructure running in AWS, such as load balancers, EC2 instances, or S3 buckets, and can route users to various AWS resources based on their geographic location or latency.

Additionally, Route 53 provides health checking for websites and can automatically redirect traffic away from unhealthy endpoints, ensuring high availability and seamless user experiences. It integrates with other AWS services, making it a powerful tool for managing DNS within the AWS ecosystem.

In contrast, the other options do not relate directly to DNS services. CloudFront is a content delivery network (CDN) that speeds up the distribution of static and dynamic web content. CloudTrail records AWS API calls for account auditing, while CloudDNS does not exist as an AWS service. Therefore, Route 53 is the correct answer as it specifically refers to AWS's DNS management service.
