A better way to ask the question would have been...
Which of the following cannot be upgraded the SQL Server 2005:
O SQL Server 2005 RTM
O SQL Server 2000 SP4 or later
O SQL Server 2000 SP3 or later
O SQL Server 7.0
O SQL Server 6.5
Bu perhaps it would then have been too easy.

Poorly worded or not, I would never do an in-place upgrade.
And, of course, the first thing to do when planning an upgrade is look at the release notes and see what the prerequisites are so this question is a bit academic.:D
