We’re being asked to determine the metal that can be oxidized by Sn2+ but not by Fe2+.
Recall that the activity series gives us the relative reactivities of metals to oxidation: metals higher in the activity series are more reactive to oxidation and vice-versa.
Which of the following reagents would oxidize Cr to Cr2, but not Ag to Ag?
