Best answer
Right option is (d) diethyl cadmium

The explanation: For butan-2-one to form from acetyl chloride, the Cl group needs to be replaced by an ethyl group. This ethyl group is obtained from diethyl cadmium which is produced from the reaction between ethyl magnesium bromide and cadmium chloride.
