Best answer
Right choice is (b) Sulphite oxidation technique

The best explanation: The sulphite oxidation balance technique does not require the measurement of dissolved oxygen concentration. It depends on the rate of conversion of sodium sulphite solution to sodium sulphate solution in the presence of a catalyst.
