D) A network client uses the subnet mask to determine whether the destination IP address is on the LAN. If the destination IP address isn't on the LAN, it's assumed the destination address is on another network, and the client sends the data to the IP address of the local network router. The network router then sends the data, via a WAN connection, on to another router that it thinks is closer to the destination. This continues across WAN connections from router to router until the data reaches its destination.
