On dissolving sugar in water at room temperature it feels cool to the touch. Under which of the following cases, dissolution of sugar will be most rapid?

Given :
\(\begin{array}{l}
E_{K^{+} / K}^{\circ}=-2.93 V \\
E_{Ag^{+} / Ag}^{\circ}=0.80 V \\
E_{Hg^{2+} / Hg}^{\circ}=0.79 V \\
E_{Mg^{2+} / Mg^{-}}^{\circ}=-2.37 V \\
E_{Cr^{3+} / Gr}^{\circ}=-0.74 V
\end{array}\)
Choose the correct order :
(A) \(Ag < Hg < Cr < Mg < K\) (increasing reducing power)
(B) \(Ag < Hg < Cr < Mg < K\) (decreasing oxidising power)
(C) \(Ag > Hg > Cr > Mg > K\) (decreasing oxidising power)
(D) \(Hg > Cr > Ag > K > Mg\) (increasing reactivity )
(E) \(K > Mg > Cr > Hg > Ag\) (decreasing reactivity order)

Read the passage carefully and answer the questions
The coordination compounds are of great importance. These compounds are widely present in the mineral, plants and animal world and are known to play many important functions in the area of analytical chemistry, metallurgy, biological systems, industry and medicine. For example, coordination compounds find use in many qualitative and quantitative chemical analysis. Some important metal extraction and purification make use of complex formation. Hardness of water can be estimated by stable complex formation of Ca\(^{2+}\) and Mg\(^{2+}\)
