I agree the use of the word "only" means the statement precludes any of the other answers from being chosen at all.

I got it right but I assumed that the author just choose poor wording and made the choice as follows

7.0 SP4 is valid

2K SP3 + is valid

2K SP4 would be included in SP3 and up

that left 2005 RTM considering applying SP1 or SP2 as in place upgrade.

I was worried that the author wanted the first choice to be wrong because you are already on 200t but because the RTM was there I figured he or she was looking for applying the SP.

Half the questions posted here are unclear and require too many assumptions.

Just my opinion
