Why each option

IPv6 defines three address types - unicast, multicast, and anycast - and explicitly eliminates broadcast addressing to improve network efficiency and scalability.

AUnicastCorrect

Unicast addresses identify a single network interface and deliver packets exclusively to that one destination, making it a foundational IPv6 address type inherited and refined from IPv4.

BMulticastCorrect

Multicast addresses identify a group of interfaces simultaneously, delivering packets to all group members and absorbing many functions that broadcast served in IPv4.

CBroadcast

Broadcast addressing was deliberately removed from IPv6; the IPv6 specification replaced broadcast with targeted multicast groups, eliminating the overhead of forcing all nodes on a segment to process every broadcast frame.

DAnycastCorrect

Anycast addresses are assigned to multiple interfaces across different nodes, and packets sent to an anycast address are routed to the topologically nearest interface holding that address - a capability unique to IPv6.
