To answer this question, we need to understand what a broadcast domain is and how it is created.
A broadcast domain is a logical division of a network where all devices can reach each other using broadcast messages. Broadcast messages are used by devices to communicate with all other devices on the same network segment.
A router is a networking device that connects multiple networks and allows communication between them. Each interface on a router represents a different network segment. When a broadcast message is sent by a device on one network segment, it is not forwarded to other network segments by the router, which means that each network segment connected to a router represents a separate broadcast domain.
In the given scenario, we have 3 hosts connected to one port of the router and 2 other hosts connected to another port of the same router. Since each port on a router represents a different network segment, we can assume that the router has two network segments.
Therefore, the router has two broadcast domains, one for each network segment. Hence, the answer is option B, which states that there are 2 broadcast domains on the router.
