Which solution would help a college alleviate network congestion due to collisions?

a firewall that connects to two Internet providers
a high port density switch
a router with two Ethernet ports
a router with three Ethernet ports

Explanation: Switches provide microsegmentation so that one device does not compete for the same Ethernet network bandwidth with another network device, thus practically eliminating collisions. A high port density switch provides very fast connectivity for many devices.
