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:

Which of the following ionic combinations may lead to the formation of explosive substance?

A

sodium ion and azide ion

B

silver ion and perchlorate ion

C

silver ion and azide ion

D

`Fe^(3+)` ion and azide ion
