Which routing algorithm uses the hop count as the metric ?
Answer: B
The algorithm is RIP (Routing Information Protocol).
RIP is a distance-vector protocol whose only metric is hop count, the number of routers on the path. It allows at most 15 hops, and 16 is treated as unreachable, which limits it to small networks.
OSPF is a link-state protocol that uses a cost usually based on bandwidth. BGP chooses routes between autonomous systems using path attributes and policy. EIGRP uses a composite metric of mainly bandwidth and delay.
