Consider the following four electrodes:

A = Cu²⁺ (0.0001 M)/Cu _(s)

B = Cu²⁺ (0.1 M)/Cu _(s)

C = Cu²⁺ (0.01 M)/Cu _(s)

D = Cu²⁺ (0.001 M)/Cu _(s)

If the standard reduction potential of Cu is + 0.34V, the reduction potentials (in volts) of the above electrodes follow the order

• A

  A > D > C > B

• B

   B > C > D > A

• C

  C > D > B > A

• D

   A > B > C > D
