Correct answer is B as per this doc. https://cloud.google.com/network-connectivity/docs/vpn/concepts/choosing-networks-routing#ts-ip-ranges “When you use IKEv1, you can only supply a single CIDR for the local traffic selector and a single CIDR for the remote traffic selector. … Cloud VPN does not support creating a VPN tunnel by using IKEv1 with multiple Child SAs, each with a single CIDR.”
