Answer

The correct answer is D. The structural formula for glycerol (glycerin) is represented as CH2_2OH - CHOH - CH2_2OH. This structure shows that glycerol has three hydroxyl (–OH) groups, characteristic of a triol. In contrast, options A, B, and C do not adequately represent glycerol's structural arrangement.
