The router forwards traffic based on the best matching route in the routing table. For a destination host such as
10.0.1.5, the router compares available prefixes and selects the route with the longest matching prefix. After selecting the route, it forwards the packet to the next-hop address listed for that route, not necessarily to the final destination directly. In this exhibit, the route that includes 10.0.1.5 points to 10.0.1.50 as the next hop.
That makes 10.0.1.50 the Layer 3 neighbor to which the packet is sent next. Cisco CCNA 200-301 v1.1 IP Connectivity expects engineers to read routing output accurately: destination prefix, administrative distance, metric, next-hop address, outgoing interface, and route source all have separate meanings. A loopback label is not a next-hop IP address, and nearby addresses in the same range are not automatically correct. The next hop is the one installed in the matching route entry, so B is correct.
