A and B talking about assigning zones to 3 VPC while we have 4 VPC in total. So A and B are wrong answers as it not reflecting given situtation. my vote would be for D even it not fully describe required solution as mentione forwarding but not mention where to firward. C maybe also kind of valid

Answers C & D would mean exposing the internal domain to the internet. Answer A would not allow each VPC to resolve the names in all zones hence Answer B.

For each private hosted you create, multiple VPCs can be associated.

I see nothing in your link that points to answer B. In the link they are talking about overlapping namespaces which is the scenario in answer A. Overlapping namespaces: https://aws.amazon.com/about-aws/whats-new/2019/11/amazon-route-53-now-supports-overlapping-namespaces-for-private-hosted-zones/ A is my answer

Why not B ? if a single hosted zone can work with subdomain records , then why not ?

They emphasize "following 4 zones". B can work but make it become 1 zone and not good for management.

Indeed. The link suggested by jvndmt supports answer A with Route 53 setup for each VPC
