The correct option is C Rotate polarised light to right
Saccharides having asymmetric carbons (carbon fulfill its valency with a different group of atoms) are able to rotate polarised light. If polarised light rotates to right side means dextrorotatory (denoted by D, d or +). If polarised light rotates to left means Laevorotatory ( denoted by L, l or -). Among sugars Dextrorotatory are common. Thus, the correct option is B.
