Refer to the exhibit. EIGRP has been configured on al l routers in the network. The command metric weights 0 0 1 0 0 has been added to the EIGRP process so that only the delay metric is used in the path calculations. Which router will R1 select as the successor and feasible successor for Network A?（）A. R 4 becomes the successor for Network A and will be placed in the routing table. R2 becomes the feasible successor for Network AB. R4 becomes the successor for Network A and will be included in the routing table. No feasible successor will be selected a s the advertised distance from R2 is higher than the feasible distanceC. R2 becomes the successor and will be placed in the routing table. R4 becomes the feasible successor for Network AD. R2 becomes the successor and will be placed in the routing t able. No feasible successor will be selected as the reported distance from R4 is lower than the feasible distance
