Your manager comes to you because he has discovered that there is a lot of broadcast traffic going across his network. He/She is thinking about splitting up his network with bridges. You inform him/her that they should get a router(s) instead. Why?

a) Routers have less latency when they are forwarding frames and packets. b) Routers work only at the data-link layer and are capable of running many protocols. c) Routers, unlike bridges, do not forward broadcast packets. They segment the network and create smaller collision domains. This means that they will stop broadcast storms. d) You just wanted to disagree with the boss. There is no advantage to having routers for segmentation instead of bridges.
