Huge NAT gateway charges

An AWS bill shows large NAT Gateway data processing charges. Private-subnet nodes pull big images from ECR and read terabytes from S3 in the same region. What is the best fix?

A.Move all nodes into public subnets with public IPs, so they no longer need any NAT gateway.B.Add an S3 gateway endpoint and ECR interface endpoints so the traffic skips the NAT gateway.C.Add more NAT gateways, one per private subnet, so the per-gigabyte processing load is spread out evenly.D.Compress all S3 objects and image layers so that less data passes through the NAT gateway.
