Refer to the exhibit. Router B is performing bidirectional redistribution between EIGRP an d OSPF.The network 10.100.1.0/24 should not be reachable from the 10.100.9.0/24 network. However, it needs to be reachable from any network within the EIGRP domain. All other networks should be seen in both domains. Which change to router B would accom plish these goals?（）

• A、Under the EIGRP process, insert the distribute - list block_net_1 out ospf 1 command.
• B、Under the OSPF process, insert the distribute - list block_net_1 in serial1/0 command.
• C、Under the EIGRP process, insert the distribute - list  block_net_1 in serial1/0 command.
• D、Under the OSPF process, insert the distribute - list block_net_1 out eigrp 1 command.
