Selected Answer: D

ALIAS records are specific to AWS and provide a way to achieve the benefits of a CNAME record (such as flexible resource updates and load balancing) while allowing you to use the apex domain. The ALIAS record acts like a CNAME but is resolved to the underlying AWS resource at the DNS level, providing better performance and compatibility. Therefore, to point the website's apex domain name to the Application Load Balancer, you should set an ALIAS record in Route 53.
