Standard reduction potentials (SRP) for ...

Standard reduction potentials (SRP) for different systems can be used to decide the spontaneity of a reaction e.g., `E_(2n^(2+)//Zn)^(@)=-0.76V`, hence for the reaction `Zn+2H^(+)rarrZn^(2+)+H_(2),DeltaG^(@)` is negative. It has been found experimentally that if (SRP of an oxidant-SRP of a reductant) is more than 1.7V, then their combination may lead to explosion (though it may be prevented by kinetic factors).
Now go through the following data and answer the questions.
Data:

A

`Fe^(3+)`

B

`Fe^(2+)`
