When aniline reacts with NaNO_2 and dil. HCl at 0^@-%^2C , the product formed is

A hydrocarbon 'A' (C_(4)H_(8)) on reaction HCl gives a compound 'B', (C_(4)H_(9)Cl) which on reaction with 1 mol of NH_(3) gives compounds 'C' (C_(4)H_(11)N) . On reacting with NaNO_(2) and HCl followed by treatment with water compound 'C' yields an optically active alcohol, 'D'. Ozonolysis of 'A' given 2mols of acetyldehyde. Identify compound 'A' to 'D'. Explain the reaction involved.
