I think the most appropriate answer is B !
as electrolysis is non spontaneous ! and it is also a redox rkn !
I think the correct answer is option 3. CaCl2 is the compound that is an electrolyte when dissolved in water. An electrolyte is a substance that conducts electricity in solution. Calcium Chloride when in solution dissociates into ions which allows the flow of current in the solution.
Answer:
iron i believe is ionic and carbon is covalent
