Which combination of architectural changes will reduce the NAT gateway costs?

A company has deployed an API in a VPC behind an internet-facing Application Load Balancer (ALB). An application that consumes the API as a client is deployed in a second account in private subnets behind a NAT gateway. When requests to the client application increase, the NAT gateway costs are higher than expected. A solutions architect has configured the ALB to be internal.

Which combination of architectural changes will reduce the NAT gateway costs? (Choose two.)
A . Configure a VPC peering connection between the two VPCs. Access the API using the private address.
B . Configure an AWS Direct Connect connection between the two VPCs. Access the API using the private address.
C . Configure a ClassicLink connection for the API into the client VP
D . Access the API using the ClassicLink address.
E . Configure a PrivateLink connection for the API into the client VP
F . Access the API using the PrivateLink address.
G . Configure an AWS Resource Access Manager connection between the two accounts. Access the API using the private address.
