(Given: specific rotations of ($+$)-sucrose, ($+$)-maltose, $L$-($-$)-glucose anc. $+(+)$-fructose in aqueous solution are $+66^{\circ},+140^{\circ},-52^{\circ}$ and $+92^{\circ}$, respectively)
($A$) 'invert sugar' is prepared by acid catalyzed hydrolysis of maltose
($B$) . 'invert sugar' is an equimolar mixture of $D$-($+$)-glucose and $D$-($-$)-fructose
($C$) specific rotation of 'invert sugar' is $-20^{\circ}$
($D$) on reaction with $\mathrm{Br}_2$ water, 'invert sugar' forms saccharic acid as one of the products
$C{H_3} - C \equiv N\xrightarrow[{E{t_2}O}]{{C{H_3}Mgl}}\xrightarrow{{{H_3}{O^ \oplus }}}$
$2CHI_3 + 6Ag \to 6AgI(s) + C_2H_2(g)$
