Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

-ve potential means the process is not feasible.
Here reduction potential of A is negative
Meaning reduction of A is not possible.
But when you reverse the process i.e A- = A + e- it's potential will become positive
Now positive potential means process is feasible.
Now you can solve the problem accordingly check if the proces is oxidation ( removal of electron)
A- oxidation is feasible.
option D is correct
