I think it's C. Please mark brainliest
Solution :
Cd(s) ----------------------> 
(aq) + 2
, 
= 0.34 v
(aq) + 2 ------------> Cu (s) , = -0.04 v
----------------------------------------------------------------------------------------------
Cd(s) + (aq) -------------> (aq) + Cu (s) , = 0.30 v
The cell potential is defined as the measure of 
between the
