Selected Answer: D
An alias record in Amazon Route 53 is used to map a domain's zone apex (also known as the root domain or apex domain) to another AWS resource, such as an ELB Application Load Balancer. It provides a seamless and efficient way to direct traffic from the root domain to the desired endpoint.

will go with D - CNAME cant be used - Default answer cant be true since A record points to an IP address not the a domain name - AAA is for IPv6

https://aws.amazon.com/route53/faqs/ Can I point my zone apex (example.com versus www.example.com) at my Elastic Load Balancer? Yes. Amazon Route 53 offers a special type of record called an 'Alias' record that lets you map your zone apex (example.com) DNS name to the DNS name for your ELB load balancer (such as my-loadbalancer-1234567890.us-west-2.elb.amazonaws.com) https://docs.aws.amazon.com/govcloud-us/latest/UserGuide/setting-up-route53-zoneapex-elb.html
