Given below are two statements.  
Statement I:  Cellulose is a polymeric polysaccharide.
Statement II:  The building blocks of cellulose are glucose molecules. 
In the light of given statements, choose the correct answer from the options given below.

Both statement I and statement II are correct.
SI: Cellulose is indeed a polysaccharide, which means that it is a complex carbohydrate made up of repeating
units of monosaccharides. 
SII: Cellulose is a polysaccharide made up of linear chains of glucose units linked together by $\mathrm{\alpha }$-1,4-glycosidic bonds. Each glucose molecule contributes to the formation of the cellulose chain, and the long chains are responsible for the structural strength and rigidity of cellulose, making it a vital component of plant cell walls.
