The correct match for the IPv6 multicast scope FF02 is link-local. This is because the FF02 prefix represents multicast addresses that are only intended to be used within a single link or network segment. Multicast addresses with this scope are not routable beyond the local link, making them suitable for communication between devices that are directly connected to the same network segment.

This local scope is often utilized for protocols that need to send messages to all nodes on the local link, such as Neighbor Discovery Protocol (NDP) and the Stateless Address Autoconfiguration (SLAAC). The link-local scope enables these protocols to function effectively without relying on routing, ensuring that all multicast traffic marked with FF02 reaches only the intended receivers on the same network segment.

In contrast, the other scopes mentioned don't align with the functionality of FF02. Global scopes would allow multicast traffic to be routed across different networks, site-local is more extensive than link-local, and interface-local pertains only to the individual interface on a device, failing to encompass the broader multicast purpose implied by FF02. Thus, understanding these scopes helps clarify how different multicast addresses operate within specific networking contexts.
