The correct answer is B.

Explanation:

In stereoisomers, isomers differ in the orientation or spatial arrangement of their atoms.

The bonds of carbon atoms are three-dimensional geometry, their bonds can rotate in such a way that they offer a multitude of alternative positions. This allows the existence of the different stereoisomers of monosaccharides.
