```							Hiii RatherFrom my point of view the option D should be not the ans.Option D should be x+y = z not x+y = 2zIf this option will correct then both c and d would be correct.

```							Correct option : (c) Explanation:  Here, KIO3 + 5KI + 3H2SO4 → 3I2 + 3H2O + 3K2SO4 And 6Na2S2O3 + 3I2 → 3Na2S4O6 + 6NaI From the above two chemical equation, x = 1, y = 5 and  z =6Now, KIO3 + 6Na2S2O3 + 3H2SO4 → 3NaS4O6 + KI + 3H2O + 3Na2SO4 We have , Coa (Concentration of oxidising agent) x Voa (volume of oxidising agent)/ 1 = Cra x Vra (Reducing agent) / 6 = > x/1 = z/6 [v = 1 (assumed)] => z = 6x Similarly, when we will have KI as the oxidising agent and Na2S2O3 as the reducing agent : y/5 = z/6  => 6y = 5z Now, x + y = (1 + 5) = 6  = z so, option (c)
