Explanation / Answer

None of the above as you have to measure number of viable cell which can be determine bye the serial dilution sample with plate pouring and counting CFU next day of the plate.

redox change will not tell the viable cell amount as it just determine the chemical reaction took place, electrical charge is not carry by the cell and turbidity just tell you about presence of cell not about viable cell count.
