Which interface forwards traffic toward the destination network?

The correct answer is F0/12 because it is the interface connected to the destination network. In network routing, a router's primary function is to forward packets to their intended destination. This is achieved by consulting its routing table, which maps destination networks to outgoing interfaces. The router will identify the entry in its routing table that matches the destination IP address of the incoming packet and then forward that packet out through the corresponding interface. The other interfaces (F0/5, F0/6, F0/9) are incorrect because they are not directly connected to the destination network and would not be the egress interface for traffic destined for that network, according to the routing table.
