    Cellulose on hydrolysis gives,

    A)  D-glucose         

    B)  D-ribose

    C)  L-glucose          

    D)  D-fructose

    Correct Answer: A

    Solution :

                    Cellulose is a polysaccharide, having monomer unit of D-glucose units which are joined by \[\beta \]-glycosidic linkages, therefore on complete hydrolysis of cellulose, D-glucose is formed. \[\underset{Cellulose}{\mathop{{{({{C}_{6}}{{H}_{10}}{{O}_{5}})}_{n}}}}\,+n{{H}_{2}}O\xrightarrow{{{H}^{+}}}\underset{D\text{-}glucose}{\mathop{n{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,\]
