Router R1 has working interfaces S0/0, S0/1, and S0/2, with IP address/prefix combinations of 10.10.10.1/24, 10.10.11.2/24, and 10.10.12.3/22. R1‘s configuration includes the command s router eigrp 9 and network 10.0.0.0. The show ip eigrp interfaces command lists S0/0 and S0/1 in the command output, but not S0/2.Which answer gives the reason for the omission？（）A. R1 has EIGRP neighbors reachable via S0/0 and S0/1, but not via S0/2, so it is not included.B. S0/2 may currently be in a state other than up/up.C. The network 10.0.0.0 command requires the use of mask 255.0.0.0 due to EIGRP being classful by default.D. S0/2 may be configured as a passive inter face.
