The coefficients of 

\;{\mathrm{I}^ - },\mathrm{\;\;IO}_3^ - \mathrm{\;}\,\,\mathrm{and\;}{\mathrm{H}^ + }

 in the redox reaction, 

{I^ - } + \;IO_3^ - + {H^ + } \to {I_2} + {H_2}O

 in the balanced form respectively are

View answer and explanation

Correct option: A

5,1,6

Option A (5,1,6) is correct because the balanced redox reaction requires 5 iodide ions, 1 iodate ion, and 6 hydrogen ions.
