Why each option

A star topology uses a central switch or hub through which all network traffic must pass before reaching any other device.

AMesh

A mesh topology provides direct point-to-point connections between multiple devices, so no single device handles all traffic.

BStarCorrect

In a star topology, every node on the network connects to a single central switch or hub. Room five's switch serves as that central point, requiring all packets from every other room to pass through it before reaching any destination - which is the defining characteristic of a star topology.

CBus

A bus topology connects all devices along one shared cable backbone, not through a centralized switching device.

DHybrid

A hybrid topology combines two or more distinct topology types; this scenario describes a single, uniform star arrangement.
