Options

A. 3 2 5 1 4
B. 4 1 5 2 3
C. 3 5 1 4 2
D. 3 2 1 4 5

Explanation

The electrode with greater negative value of standard reduction potential acts as anode. The electrode with greater positive value of standard reduction potential acts as cathode. Oxidation takes placed at anode and reduction takes place at cathode. X
