In a Fischer projection of a monosaccharide, a D-configuration is indicated by the orientation of the hydroxyl group on the highest numbered chiral carbon being drawn on the

A. Left side
B. Right side
✓
C. Top of the carbon chain
D. Bottom of the carbon chain

📝 Explanation

The D/L nomenclature is a convention based on glyceraldehyde. A sugar is D if the -OH group on the chiral carbon farthest from the carbonyl group (the highest numbered chiral center) is drawn on the right side in a standard Fischer projection.
