Explanation

A router operates at Layer 3 (Network layer) and enables communication between different broadcast domains by routing IP packets from one network/subnet to another. Each broadcast domain is its own Layer 2 segment, and only a Layer 3 device like a router can forward traffic between them. Switches (C) operate at Layer 2 and forward traffic within a single broadcast domain. Firewalls (B) can route between domains but their primary role is security policy enforcement. Load balancers (D) distribute traffic across servers but do not inherently route between broadcast domains.
