Explanation

Private Google Access enables VM instances that have only internal (RFC 1918) IP addresses - no external IP - to reach Google APIs and services such as Cloud Storage over Google's internal network without traversing the public internet. It is enabled at the subnet level. Option A (Carrier Peering) is used by service providers to connect their networks to Google's edge network, not for VMs accessing Google APIs. Option B (VPC Network Peering) connects two VPC networks together, not VMs to Google APIs. Option C (Shared VPC) shares a VPC across projects for centralized network management but does not by itself enable API access from instances without public IPs.
