(D) The reaction involves the nucleophilic attack of the Grignard reagent $(CH_3MgBr)$ on the carbonyl carbon of $5$-chloropentan-$2$-one. This forms an alkoxide intermediate: $Cl-(CH_2)_3-C(CH_3)_2-O^-$. Since the molecule contains both a nucleophilic alkoxide group and an electrophilic alkyl chloride group at a distance that allows for the formation of a stable five-membered ring,an intramolecular nucleophilic substitution $(S_N2)$ occurs. The oxygen atom attacks the carbon attached to the chlorine atom,displacing the chloride ion $(Cl^-)$ to form $2,2$-dimethyltetrahydrofuran.

The major product in the following reaction is:
