$HI \rightleftharpoons \frac {1}{2} H_{2(g)} + \frac{1}{2} I_{2(g)}$

is $8.0$. The equilibrium constant of the reaction

$H_{2( g )} + I_{2(g)} \rightleftharpoons   2HI_{ ( g )}$ will be

$A\, \rightleftharpoons \,B$                     ${K_C} = 2$

$B\, \rightleftharpoons \,C$                    ${K_C} = 3$

$C\, \rightleftharpoons \,D+E$               ${K_C} = 5$

$K_C$ for the reaction $A\, \rightleftharpoons \,D+E$ is

${I^ - } + \,ClO_3^-  + \,{H_2}S{O_4}\, \to \,C{l^ - }\, + \,HSO_4^ - \, + \,{I_2}$

(no free $H^+$ is present). Select the correct statement in the balanced equation (Coefficients in smallest whole number ratio.)
