The scenario indicates that users on one subnet cannot reach another subnet, where the network resources are located, after a new router configuration was implemented. A likely reason for this issue is that a necessary route is missing in the routing table of the new router. The routing table is responsible for holding the information necessary to forward packets to the correct destinations. If a route for the particular destination subnet is missing, the router will not be able to forward traffic to that subnet. Incorrect gateway would not directly relate to the new router configuration as that would typically present as an issue with accessing all network resources, not just those on a particular subnet. Incorrect subnet mask would be relevant if the problem were with address configuration on the workstations and incorrect VLAN would be a plausible choice if the issue were with traffic separation within the same broadcast domain, but incorrectly relates to a Layer 2 issue, not Layer 3 routing.
