An unknown aldehyde 'A' on reacting with alkali gives a beta hydroxy aldehyde, which losses water to form an unsaturated aldehyde, but-2-enal. Another aldehyde 'B' undergoes disproportionation reaction in the presence of conc alkali to form products 'C' and 'D'. 'C' is an aryl alcohol with formula C_7H_8O : Identify A and B.
