You are right but in practice in this case there isn't much difference.

Anybody, following GPLv2, can just redistribute it under GPLv3, and
you *could* track each file as to GPLv2, v3, or mixed. But that would
be a lot of bureaucracy that wouldn't help anyone -- anybody
interested in GPLv2 sources should just go to the last commit or
release under v2.

Honestly, option b is rather annoying if relevant authors/owners of
the copyright aren't in agreement. But it has notthing illegal.

The "copyright lines" are advisory only, and nonbinding. Of course,
courts look unfavourably upon knowing infringers that remove (as upon
anyone found hiding evidence) them but they aren't sacred in the
normal course of things.
