How can the domain's zone apex for example "myzoneapexdomain com" be pointed towards an Elastic Load Balancer?

Suggested Answer: D 🗳️
Alias resource record sets are virtual records that work like CNAME records. But they differ from CNAME records in that they are not visible to resolvers.
Resolvers only see the A record and the resulting IP address of the target record. As such, unlike CNAME records, alias resource record sets are available to configure a zone apex (also known as a root domain or naked domain) in a dynamic environment.
