Solution:

The six membered cyclic structure of glucose is called pyranose structure ( $\alpha$ or $\beta$ ), 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 correctly represented by Haworth structure.
