Question

The following are some statements about electrolytic cell
A) in this, chemical energy converted into electrical energy
B) in this cell, electrons flow from cathode to anode
C) in this, cell reduction takes place at cathode
D) in this, cathode is a +ve electrode
The correct combination is

Easy

A

only B
B

only C
C

only C, D
D

only B, C
