(D) The Molisch test is a general chemical test for the presence of carbohydrates. It involves the reaction of carbohydrates with $\alpha$-naphthol in the presence of concentrated $H_2SO_4$ to form a purple or violet ring at the interface. Since all carbohydrates (monosaccharides,disaccharides,and polysaccharides) undergo this reaction,all of them give a positive Molisch test.
