Correct answer: C
Answer: C (Ring)
In a standard ring topology, nodes form a closed loop. Data is passed from one node to the next.
Because each node is part of the forwarding path, failure of one individual node can break the loop and disturb the whole network communication.
In a bus topology, the important distinction is that the backbone cable can affect the whole network. Failure of one attached node is different and usually does not stop the remaining nodes.
So the topology asked in the question is Ring, not Bus.
