$BrO_{3(aq)}^ - \, + \,5Br_{(aq)}^ - \, + \,6{H^ - }\, \to \,3B{r_{2(l)}}\, + \,3{H_2}{o_{(l)}}.$
The rate of appearance of bromine $(Br_2)$ is related to rate of disappearance of bromide ions as

$A^+/A = \,-\,2.93\, Volt$, $B^+/B = 0.80\,V$
$C^{+2}/C = \,-\,2.37\, Volt$, $D^{+3}/D = \,-\,0.74\,V$
Increasing order of reducing power of these metals
