B Correct answer
Explanation

Routers operate at Layer 3 (Network Layer) and make forwarding decisions based on IP network addresses and network classes (Class A, B, C), not individual MAC addresses. They route packets between different networks. Bridges and switches work at Layer 2 using MAC addresses, while hubs simply repeat signals to all ports without any decision-making capability. Only routers use network address groups for routing decisions.
