Solution

The correct option is C Acetone
Polar aprotic solvent favours $S_{N} 2$ reaction because polar aprotic solvent is unable to solvate the nucleophile.
So, the nucleophilicity of a nucleophile does not decrease in such solvent. Both DMSO and acetone are polar aprotic solvent hence they favour $S_{N} 2$ reaction.
Ethanol and water are polar protic solvent and hence both favours $S_{N} 1$ reaction.
