Hint: The monomer of cellulose is an aldohexose. An aldohexose is a sugar containing 6 Carbon atoms and an aldehydic group.

Complete step by step answer:
Cellulose is an important component of the cell walls in plants. It is present as microfibrils of plant cell wall. Thus, it is the structural component of plant cell wall and primitive fungi. Cellulose is also used for the production of papers. Cellulose is non reducing sugar as aldehyde group is not free. Aldehyde group is involved in glycosidic bond formation.
Cellulose is a fibrous, straight chain polymer. It is a polysaccharide consisting of several glucose units joined by glycosidic bonds. The glycosidic linkage is between C-1 of one glucose unit and C-4 of other glucose unit. Cellulose is also called glucosan homopolysaccharide. One linear chain of cellulose contains around 6000 to 10000 glucose units. Cellulose is also called hexosan polysaccharide because the monomer glucose is a hexose sugar.
The structure of glucose is as shown below:

The structure of cellulose is as shown below:

Hence, the option A ) glucose is the correct answer.

Note:
Sucrose is a disaccharide which gives glucose and fructose on hydrolysis. Cellulose is a polymer of a monosaccharide.
