The correct answer is D. Create 1 VPC with 2 regional subnets. We create one VPC network in auto mode that creates one subnet in each Google Cloud region So, region us-east1 and europe-west1 are in the same network and they can communicate using their internal IP address even though they are in different Regions.

Explanation

We create one VPC network in auto mode that creates one subnet in each Google Cloud region So, region us-east1 and europe-west1 are in the same network and they can communicate using their internal IP address even though they are in different Regions. They take advantage of Google's global fiber network. https://cloud.google.com/vpc/docs/using-vpc#create-auto-network
