The correct options are
A Oxidation of D-galactose by HNO3 gives a meso product
B Aldose reacts with Fehling's solution, but not with NaHSO3
D D-fructose and D-glucose can be differentiated using bromine water
Aldose has a cyclic structure which cannot react with NaHSO3.
Br2/H2O being a mild oxidising agent can only oxidise aldose to carboxylic acids but cannot oxidise ketoses.
