The condition for tautomerism is that 
-hydrogen must be present in the molecule. Thus,
molecule II will not show tautomerism. As at bridge, double bond is highly unstable. Thus, molecule I will also not show tautomerism.
For III molecule,
So only, III molecule will show tautomerism. Thus, correct option is .
