Explanation

A router operates at Layer 3 (Network layer) of the OSI model and is specifically designed to forward packets between different networks by examining destination IP addresses and consulting its routing table. A switch (D) operates at Layer 2 and forwards frames within the same network segment (LAN). A firewall (C) filters traffic based on security rules but is not primarily responsible for routing between networks. A load balancer (B) distributes incoming traffic across multiple servers to optimize resource usage but does not route packets between disparate networks.
