    B

    R1 and R2 are the DR and BDR, so OSPF will not establish neighbor adjacency with R3.

    C

    A static route has been configured from R1 to R3 and prevents the neighbor adjacency from being established.

    D

    The hello and dead interval timers are not set to the same values on R1 and R3.
