Selected Answer: C
Protocol forwarding uses a regional forwarding rule to deliver packets of a specific protocol to a single virtual machine (VM) instance. The forwarding rule can have an internal or an external IP address. Protocol forwarding delivers packets while preserving the destination IP address of the forwarding rule. The forwarding rule references an object called a target instance, which, in turn, references a single VM instance https://cloud.google.com/load-balancing/docs/protocol-forwarding#target-instances
