Solution

The correct option is D all of above
When electric current passes through a conducting solution, it causes chemical reactions. This is called electrolysis and the effect is the chemical effects of electric current. The chemical effect of electric current may cause the formation of gas bubbles at the electrodes, deposition of metal on the electrodes and change in colour of the solution.
