Solution

The correct option is C Hydrogen bonding with adjacent glucose polymer.
The rigidity and stiffness of cellulose is due to hydrogen bonding with adjacent glucose polymer. The hydrogen bonding is observed between between third oxygen of one glucose unit and fifth oxygen of the preceding glucose unit. Due to this, it has high viscosity in solution and high tendency to crystallize than other polysaccharides like starch or dextran.
Thus, the correct answer is option C.
