After DUAL calculations, a router has identified a successor route, but no routes have qualified as a feasible successor. In the event that the current successor goes down, what process will EIGRP use in the selection of a new successor?（）

• A、EIGRP will automatically use the route with the lowest advertised distance (AD) .
• B、The route will transition to the active state.
• C、The route will transition to the passive state.
• D、EIGRP will find the interface with the lowest MAC address.
• E、EIGRP will automatically use the route with the lowest feasible distance (FD).
