It was close between A & D. A could have been the answer but cost doesn't affect DR/BDR. If it were "ip ospf priority 0" then yes it would not join DR/BDR election.

if ip ospf priority was set to 0 on R1, it would have only prevented from being the DR, but it would be the BDR instead.

Selected Answer: D
Why Option D is Correct OSPF Point-to-Point Network Type: Configuring ip ospf network point-to-point tells OSPF that the link is a point-to-point connection. In point-to-point OSPF network types, routers communicate directly without electing a DR/BDR

The valid range for OSPF cost is 1 to 65,53512. A cost of 0 is not allowed in OSPF.

D is correct. However, Cisco needs to do a better job laying down the design. This is a really bogus question.
