The six-membered cyclic structure of glucose is called pyranose structure (α– or β–), in analogy with pyran. Pyran is a cyclic organic compound with one oxygen atom and five carbon atoms in the ring. The cyclic structure of glucose is more correctly represented by Haworth structure

${\mathrm{C}}_2$ and ${\mathrm{C}}_3\mathrm{OH}$ are cis. ${\mathrm{C}}_3$ and ${\mathrm{C}}_4$ are anti to each other.

So,the correct option is B.
