First of all, RFC 2373 mandates that all 2000 addreses (and most others) are required
to have 64-bit interface identifiers, so the prefix in question would have to be
2000::/64 (a /96 is illegal). (Also keep in mind that you can assign many prefixes to
the same interface.)
So I'll assume it's a typo and you meant:
"Suppose the IPv6 prefix 2000::/64 is assigned to an interface."

Technically "any" one of them would be legal, but the answer that makes the most sense
is "the first one that the packet reaches" (i.e. the one closest to the source).
