    1. +1
      C is clearly wrong since the entry for 10.30.30.32 is of type unicast (ospf 100), whereas entry for 10.1.108.10 is a multicast (static).
      D is wrong as well – OSPF 100 is for the first entry.
      B – we can see the RPF topology saying “ipv4 multicast base”, the answer states “unicast”
      A seems logical in this one.
