A router breaks up which of the following?

Explanation:
A router breaks up broadcast domains. Broadcasts are sent to all devices on a local network segment, but routers don’t forward those broadcast frames from one network to another. Since each router interface connects to a different network, broadcasts don’t cross between them, so each side becomes its own broadcast domain. For context, routers do separate collision domains to some extent (each interface is its own collision domain), and they route traffic between subnets, or between VLANs when inter-VLAN routing is used. But the specific idea tested here is that a router stops broadcasts from propagating across networks, creating multiple broadcast domains.
