Explanation

A broadcast domain is a network segment where a broadcast frame sent by one device is received by all other devices. Routers operate at OSI Layer 3 (Network layer) and do NOT forward Layer 2 broadcast frames between interfaces - each router interface defines the boundary of a broadcast domain, effectively separating them. Switches (A) operate at Layer 2 and forward broadcasts to all ports within the same VLAN, keeping devices in the same broadcast domain (VLANs can segment this, but a basic switch does not). A wireless access point (B) bridges wireless clients into the same broadcast domain as the wired network. A hub (D) is a Layer 1 device that repeats all signals to every port, actually extending both collision and broadcast domains.
