The correct choice is (b) Broadcasts have been eliminated and replaced with multicasts

Best explanation: In IPv6, there’s no longer any broadcast, sending one packet to a large number of unspecified hosts. There’s only multicast, unicast and anycast. In IPv6 all nodes are required to support multicast.
