$(a)$ tetraamminecobalt $(III)$ dim-hydroxidotetra amminecobalt $(III)$ ion

$(b)$ di $-\mu -$ hydroxidobis(tetraammine)dicobalt $(III)$

$(c)$ Bis $-(\mu -$ hydroxidotetraamminecobalt $(III))$

$(d)$ di $-\mu-$ hydroxidooctaamminedicobalt $(III)$

correct option is

Statments $I:$ Maltose has two $\alpha$-D-glucose units linked at $C _{1}$ and $C _{4}$ and is a reducing sugar.

Statement $II:$ Maltose has two monosaccharides: $\alpha$-D-glucose and $\beta$-D-glucose linked at $C_{1}$ and $C_{6}$ and it is a non-reducing sugar.

In the light of the above statements, choose the correct answer from the options given below.

$Cu ( s )+ Sn ^{2+}( aq ) \rightarrow Cu ^{2+}( aq )+ Sn ( s )$

$\left( E _{ Sn ^{2+} \mid Sn }^{0}=-0.16\, V , E _{ Cu ^{2+} \mid Cu }^{0}=0.34\, V \right.$ Take $F=96500\, C\, mol ^{-1}$ )

$\left( A \right)\xrightarrow{{\operatorname{Re}duction}}\left( B \right)\xrightarrow{{HN{O_2}}}{C_2}{H_5}OH$
