Answer: VPC peering

The correct answer is B, VPC peering. VPC peering allows you to establish a private network connection between two VPCs that can be in the same or different AWS Regions. This connection uses the existing infrastructure of the VPCs and does not require the use of the public internet. AWS Direct Connect (option C) is used for creating a dedicated network connection between your on-premises data centers and AWS, which is not suitable for connecting two VPCs in different regions. AWS Client VPN (option A) is for secure remote access to your VPCs and is not designed for interconnecting VPCs. VPC endpoints (option D) are used for securely connecting your VPC to AWS services without using the public internet, not for interconnecting VPCs.
