Which of the following IPv6 address types is a single address that can be assigned to multiple interfaces?

A Unicast address identifies a single network interface and is used for one-to-one communication, where packets are delivered to that specific, unique interface.

A Multicast address identifies a group of interfaces, and packets sent to a Multicast address are delivered to all members of that group.

A Loopback address (::1) is a special Unicast address used to refer to the local host itself, primarily for testing the local machine's network stack.

An Anycast address is a unicast address that can be assigned to multiple interfaces (typically on different nodes), but a packet sent to an Anycast address is delivered to only one of these interfaces, specifically the one that is closest in terms of routing distance.
