Step 1: Haworth Projections — To convert a Fischer projection to a Haworth pyranose form, groups on the right go down, and groups on the left go up.
Step 2: Specific Orientations — For the given sugar [X], the groups at C2, C3, and C4 are appropriately positioned according to the rules of pyranose representation.
Step 3: Conclusion — Analyzing the substituents at each carbon lead to structure (b) as the correct six-membered pyranose representation for sugar [X].
Key Point: Careful mapping of C1 to C5 substituents is essential for accurate cyclic rendering.
