A company's VPC has an existing IPv4 configuration. The IPv4 configuration includes public subnets, private subnets, NAT gateways, default route tables, and ACLs.
The company associates an IPv6 CIDR block with the VPC. The company adds IPv6 allocations to each existing subnet and adds routes to the route tables. The company updates the ACLs to allow all IPv6 traffic.
Public subnets are working as expected, but private subnets are not allowing internet IPv6 connections.
What should a SysOps administrator do to allow outbound-only connectivity for the new IPv6 subnets?

A. Configure an egress-only internet gateway and associate it with the VPC. Create a default route in the route tables that are associated with the private subnets. Configure the default route to point to the egress-only internet gateway.

B. Turn on IPv6 NAT on the NAT gateways. Create a default route in the route tables that are associated with the private subnets. Configure the default route to point to the NAT gateways.

C. Configure a new IPv6-only NAT gateway. Create a default route in the route tables that are associated with the private subnets. Configure the default route to point to the IPv6-only NAT gateway.

D. Create a default route in the route tables that are associated with the private subnets. Configure the default route to point to the existing internet gateway.
