Option A seems incorrect. The question states it's received on the LHR interface, so there shouldn't be an unsuccessful RPF check against the source.

Option C makes the most sense. If the RPF check against the routing table is successful, the multicast traffic should be switched.

I agree with Devon, the multicast traffic will be dropped if the RPF check against the multicast source fails.

I believe the multicast traffic will be switched since no RPF check is performed.
