  1. I agree with answer “B”. However, the second answer may also be “D” – the PIM DR do send query messages when IGMPv1 is in use. I am unsure of “C” – specifically the meaning of the word “for” – does this mean the Join/Prune are sent on behalf of the directly connected receivers or are Join/Prune messages sent towards the receivers? If it is the latter, then “C” would be false.
