(D) The reaction proceeds in two main steps: $1$. The Grignard reagent $(CH_3MgBr)$ acts as a nucleophile and attacks the carbonyl carbon,which is a nucleophilic addition reaction. $2$. The resulting alkoxide ion then performs an intramolecular nucleophilic substitution $(S_N2)$ by attacking the carbon attached to the chlorine atom,displacing the chloride ion. $3$. The final cyclic ether product contains chiral centers,making it a chiral molecule. Therefore,all the given statements are correct.

Consider all steps and intermediates. Which of the following is a correct statement?
