Nthe process of electrolysis, current can flow through a liquid because a. hydrogen is electrically neutralized in the solution. b. negative ions are attracted to the anode. c. water molecules become negatively charged. d. cations of the electrolyte accumulate at the positive electrodes.

The correct option is B.
The electrolysis set up consist of two electrodes and a molten or liquid form of a substance that can conduct electricity. One of the electrode is positive [anode] and the other one is negative [cathode]. During the process of electrolysis, electrons from the anode are attracted to the cathode while electrons from the cathode flow to the anode, this set up electric current in the solution.
