Assuming that OSPF has been enabled on all routers in the following figure, which router is the BDR on this network?

The correct answer is C. Router D. In OSPF, the Backup Designated Router (BDR) is selected based on the highest priority and, in case of a tie, the highest router ID. Given that Router D has the appropriate settings, it is designated as the BDR, providing backup for the DR (Designated Router) in this network
