The correct observation in the following reactions is $\text{ Sucrose }\frac{\text{ Gly cosidic bond }}{\begin{array}{c}\text{ Cleavage }\\ \text{ (Hydrolysis) }\end{array}}\mathrm{A}+\mathrm{B}\frac{\text{ Seliwanoff's }}{\text{ reagent }}??$

Seliwanoff reagent →(Resorcinol + Conc. 
HCl]
It is used to distinguish aldoses and ketoses.
Ketoses show red colour whereas aldoese show light pink colour with Seliwanoff Reagent.
