Answer: Use Private Google Access

Private Google Access allows instances without public IP addresses to access Google APIs and services, such as the Cloud Storage API, by routing the traffic through Google's private network. Enabling Private Google Access on the subnet where the instance is located ensures that the request to the Cloud Storage API does not require a public IP. Other options like VPC Peering (B) or Shared VPC (C) relate to network connectivity between VPCs but do not directly enable access to Google APIs. Carrier Peering (A) is unrelated to this scenario.
