The property of monosaccharides that allows them to be separated and identified by techniques like paper chromatography is their

A. Different solubility in non-polar solvents
B. Differential partitioning between a stationary water phase and a mobile organic solvent phase based on their polarity
✓
C. Different absorption spectra in the UV range
D. Specific radioactive decay patterns

📝 Explanation

Sugars are polar and partition between an organic mobile phase and a water stationary phase held by the paper. Slight differences in structure (e.g., number of -OH groups) cause them to partition differently and thus migrate at different rates, allowing for separation and identification.
