You work as a network engineer for. You study the exhibit carefully. Based on the output of the show command， 
what can you determine regarding EIGRP routing being performed by the switch？ （）
Exhibit：

 

A . There are 20 neighbors in the EIGRP neigbor table.
B . EIGRP is running normally and receiving IPv4 routing updates.
C . The switch has not established any neighbor relationships. Further network testing and troubleshooting must be performed to determine the cause of the problem.
D . EIGRP status cannot be determined. The command show ip eigrp topology would determine the routing protocol status.
