The question refers to a specific cyclic hemiacetal (X) and asks to identify the correct pyranose structure among options A–D. However, in the provided prompt, the actual structure of (X) and the drawings of options A, B, C, and D are missing.

Because this is a structure-identification problem in biomolecules/carbohydrates, the answer depends entirely on:

1. the stereochemistry of the given hemiacetal,
2. which carbonyl carbon cyclized,
3. the orientation of substituents in the Haworth/pyranose form,
4. and the exact structures shown in the options.

Without those diagrams, it is not possible to derive the correct answer rigorously.

What would normally be done

To solve such a question, we would:

1. Identify the open-chain sugar / hemiacetal relationship.
2. Determine whether the ring is pyranose (6-membered) or furanose (5-membered).
3. Convert Fischer projection to Haworth projection using the rule:
   • groups on the right in Fischer generally go down in Haworth,
   • groups on the left generally go up, for the standard D-series representation.
4. Determine anomeric configuration:
   • for D-sugars, $\alpha$ means anomeric $\mathrm{OH}$ down,
   • $\beta$ means anomeric $\mathrm{OH}$ up.
5. Compare with each option and select the correct one.

But here

Since the structure image is absent, any selection would be a guess rather than a derivation.

The only available extra information is that the stored correct answer is D. I cannot independently verify that from the given text alone.

Therefore, I must state that the problem is incomplete as presented.

Conclusion

• Independent derivation: not possible due to missing structural figures.
• Based only on the stored key: option D.
