Answer:
D. Routers
Step-by-step explanation:
A router can be defined as an electronic hardware device used in the field of telecommunications (networking) to forward or route packets of data from computer network to another. These packets are forwarded on the internet, from one computer network until the packets reaches its destination node through a transmission control protocol and internet protocol (TCP/IP) model.
Basically, a router is a networking device that is saddled with the responsibility of selecting the pathways for forwarding data packets over multiple computer networks through the use of an internal routing table.
Hence, the internet's data pathways rely on a hardware device known as router, to route data to its destination.
