Correct answer: A
The correct answer is Option A: Router. In the OSI model, Layer 3 is known as the Network layer, which handles logical addressing and routing between different networks. Routers operate specifically at this layer and use IP addresses to determine the best path for forwarding data packets across interconnected networks. This distinguishes them from other devices that function at different layers.",
