The standard reduction potentials of Zn²⁺ | Zn, Cu²⁺|Cu and Ag⁺ |Ag are respectively – 0.76, 0.34 and 0.8V. The following cells were constructed        

    a) Zn / Zn²⁺ // Cu²⁺ / Cu        
    b) Zn / Zn²⁺ // Ag⁺ / Ag        
    c) Cu / Cu²⁺ // Ag⁺ / Ag
    What is the correct order of E⁰_cell of these cells ?

• A

  b > c > a

• B

  b > a > c

• C

  a > b > c    

• D

  c > a > b
