Correct answer
DB > C > A
Step-by-step explanation
\matrix{
A & B & C \cr
{ + 0.5C} & { - 3.0V} & { - 1.2V} \cr
}
NOTE : The higher the negative value of reduction potential, the more is the reducing power.
Hence
NOTE : The higher the negative value of reduction potential, the more is the reducing power.
Hence
