Correct answer
BD-glucose
Step-by-step explanation
Cellulose is a linear polymer of glucose in which of one glucose unit is connected to of the other through glucosidic linkage. It does not undergo hydrolysis easily. However on heating with dilute under pressure. It does undergo hydrolysis to give only glucose.
