Assertion (A) D (+) - Glucose is dextrorotatory in nature.
Reason (R) 'D' represents its dextrorotatory nature.
Assertion (A) Vitmin D can be stored in our body.
Reason (R) Vitamin D is fat soluble vitamin.
Assertion (A) $\beta$-glycosidic linkage is present in maltose.
Reason (R) Maltose is composed of two glucose units in which $\mathrm{C}-1$ of one glucose unit is linked to $\mathrm{C}-4$ of another glucose unit.
