(i) changes with the change of electrolyte.

(ii) changes with the change of concentration of electrolyte.

(iii) changes with the temperature of the electrolyte.

(iv) remains constant for a cell.

Correct Answer: (iv) remains constant for a cell

Explanation:  K which is the cell constant is equal to the distance between the electrodes and the probe is separated by an area above the electrodes by cm². In a particular operating cell, the cell remains the same even if the electrolyte is changed. Concentration and temperature of the electrolyte is changed.
