Correct = B.
D is incorrect per: 'EIGRP vs OSPF: CPU Usage.OSPF maintains the complete information about the routers in its area. Each time there is a change within the area, all routers need to re-sync their database, which makes it more CPU intensive. EIGRP, on the other hand, has triggered and incremental updates and will not send all the information about the network rather just the information that has changed will be shared.'
"The IP Enhanced IGRP Route Authentication feature provides MD5 authentication of routing updates from
the EIGRP routing protocol."
