B.Use a VPN between both accounts.
C.Use a NAT Gateway between both accounts.
D.Use VPC Peering between both accounts.

Correct Answer – D
Options A and C are incorrect because these are used when private resources are required to access the Internet.

AWS Documentation mentions the following about VPC Peering:
A VPC peering connection is a networking connection between two VPCs that enables you to route traffic between them privately. Instances in either VPC can communicate with each other as if they are within the same network. You can create a VPC Peering connection between your own VPCs, with a VPC in another AWS account, or with a VPC in a different AWS Region.
