The conversion of glucose to sorbitol, a sugar alcohol used as an artificial sweetener, is an example of a chemical reaction where the aldehyde group of the sugar is

A. Oxidized to an aldonic acid
B. Reduced to a primary alcohol group
✓
C. Reacted with an amine to form a Schiff base
D. Phophorylated using ATP

📝 Explanation

Reduction of the carbonyl group of glucose (by agents like NaBH₄ or H₂ over catalyst) converts it to the sugar alcohol sorbitol (glucitol). The aldehyde (-CHO) is reduced to a primary alcohol (-CH₂OH). Oxidation would yield an acid, not an alcohol.
