Refer to the exhibit. Router C was configured so that it could form an adja cency with three OSPF neighbors, one connected to each of its three physical interfaces. Which statement is correct about router C?（）A. It is configured and functioning correctly as an OSPF internal router.B. It is configured and functioning correc tly as an ABR attached to stub area 4.C. It is configured and functioning correctly as an ASBR attached to external area 4.D. It is configured and functioning correctly as an ABR attached to totally stubby area 4.E. It is not configured correctly to function as specified.
To make OSPF area 4 totally stubby, the following command was issued on the ABR in router configuration mode: area 4 stub.Which two things need to be done to finish making area 4 a totally stubby area?（）A.
