Which of the following is true when describing a link-local address?

Packets addressed to a unicast address are delivered to a single interface.
These are like private addresses in IPv4 in that they are not meant to be routed.
These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.
These are your typical publicly routable addresses, just like a regular publicly routable address in IPv4.
