When benzyl chloride (C₆H₅CH₂Cl) reacts with magnesium metal in dry ether, it forms a Grignard reagent known as benzylmagnesium chloride (C₆H₅CH₂MgCl).
Upon treatment with water, this Grignard reagent undergoes hydrolysis to form benzyl alcohol (C₆H₅CH₂OH), which is the product 'A'.
Correct Answer: (B) Benzyl alcohol
