Answer: Set up a private hosted zone, link it to the VPC, enable both the enableDnsSupport and enableDnsHostnames attributes for the VPC, create a new VPC DHCP options set with domain-name-servers=AmazonProvidedDNS, and associate it with the VPC.

Option B is correct because it ensures that both the enableDnsSupport and enableDnsHostnames attributes are activated for the VPC, which is necessary for instances to receive public hostnames for public IP addresses. Additionally, it specifies using the AmazonProvidedDNS as the domain-name server in the new DHCP options set, which is appropriate for private hosted zones in Amazon VPC.
