What functional group allows sugar CnH2nOn to be water soluble select all that apply

Too bad there's not the options, but the answer must be the hydroxyl and carbonyl group.

The solubility of sucrose in water as well as organic solvents is very high. In non-aqueous solvents is generally lower. On the other hand, sucrose is not soluble in nonpolar solvents. This solubility in the polar solvent as well as the water is due to the hydroxyl (-OH) and carbonyl (-C = O) functions creating hydrogen bonds with the solvent molecules making it easier to dissolve.
