Answer is A, it is TRUE that apex maps only to alias… HOWEVER in this question you are mapping www subdomain to cname of the url of cloudfront… WWW is not APEX… https://repost.aws/questions/QUISgcF7I1Q9K4jzyReQiDMA/cname-for-domain-com-without-www

after more research, answer is B since it is more cost effective to create an alias (which is free) WWW that points to Cloudfront distribution URL.

Answer is A. CNAME – maps a hostname to another hostname. Example: you can’t create for example.com, but you can create for www.example.com

Option B is the correct answer because ALIAS records in Amazon Route 53 are used to map domain names directly to AWS resources like CloudFront distributions, S3 buckets, Elastic Load Balancers, and more. ALIAS records provide a more efficient and cost-effective way to route traffic to these AWS resources compared to CNAME records.
