Refer to the exhibit. EIGRP has been configured on router D. Router C is performing mutual redistribution between EI GRP and OSPF. While verifying that the redistribution is functioning properly, you discover that while router C has all of the EIGRP routes in its routing table, router A does not have any routes from the EIGRP domain. What on router C may be the cause o f the problem?（）
A. The no auto - summary command needs to be added under router eigrp 1
B. The subnets keyword was not included in the redistribute command under router ospf 1
C. The metric specified for the redistributed EIGRP routes is too large; m aking the EIGRP routes unreachable by router A
D. The default - information originate command needs to be added under router ospf 1
E. The administrative distance of either OSPF or EIGRP must be changed so that EIGRP has a higher administrative distanc e than OSPF

A. R1(config)# router eigrp 1 R1(config - router)# passive - interface serial 0
B. R1(config)# access - list 2 0 deny any R1(config)# router eigrp 1 R1(config - router)# distribute - list 20 out serial 0
C. R2(config)# access - list 20 permit any R2(config)# router eigrp 1 R2(config - router)# distribute - list 20 in serial 0
D. R1(config)# access - list 20 permit any R 1(config)# router eigrp 1 R1(config - router)# distribute - list 20 in serial 0
E. R2(config)# access - list 20 deny any R2(config)# router eigrp 1 R2(config - router)# distribute - list 20 out serial 0
F. R2(config)# router eigrp 1 R2(config - router)# passive - interface serial 0
