单项选择题 You are working as a network technician， study the exhibit carefully. Your boss has informed youthat there have been problems with the WAN that is using EIGRP routing protocol. You arerequired to troubleshoot these problems. Before going to the questions of this sim， we should have a quick review about GRE tunneling：GRE Quick Summary. The picture below shows how to configure a GRE Tunnel between two routers， notice that the"tunnel destination" must be the IP address of the interface， not of the opposite tunnel. Notice： The tunnel source on one router must be specified as the tunnel destination on the otherrouter. Below are the questions of this lab-sim. What is the reason that tunnel 5 on the HQ router is down when its companion tunnel on theBranch5 router is up？（）

A、The IP address on the tunnel interface on Branch5 is incorrect. It should be 192.168.1.16255.255.255.252

B、The tunnel source for tunnel 5 is incorrect on the HQ router. It should be serial 2/0

C、The tunnel numbers for tunnel between the HQ router and the Branch5 router do not match

D、The tunnel destination address for tunnel 5 is incorrect on the HQ router. It should be 10.2.5.1to match the interface address of the Branch5 router

E、The tunnel interface for tunnel 5 on the HQ router is in the administrative down state
