Solution:

A non-reducing sugar is one kind of carbohydrate that is not oxidised by a weak oxidising agent (an oxidising agent that oxidises aldehydes but not alcohols, such as the Tollen's reagent) in a basic aqueous solution.

{{C}_{12} {H}_{22} {O}_{11}}↙{{\Sucrose(A )}↙{(\text "Non-reducingsugar)"}}+ {H}_{2} {O} ⟶ { {C}_{6} {H}_{12} {O}_{6}}↙{\D-\glucose }+ {{C}_{6} {H}_{12} {O}_{6}}↙{\D-\fructose}

While all others, i.e. glucose, fructose and galactose are reducing sugar

Thus, sugar (A) is sucrose.
