Arranging half-cell reactions in order

Arrange the following five reduction half-cell reactions in order listing the largest positive reduction potential first and give the best oxidizing and reducing agents.

Observations:

i) A reacts spontaneously with 1 mol/L BNO3, 1 mol/L D(NO3) and dilute sulfuric acid. A does not react 1 mol/L C (NO3)

ii) B does not react spontaneously with any of the 1mol/L solutions above or with dilute sulfuric acid.

iii) C reacts spontaneously with dilute sulfuric acid and with 1 mol/L solutions of all other metallic salts.

iv) D reacts spontaneously with 1mol/L B(NO3). It does not react with dilute sulfuric acid.

a) Use the observations and arrange the following five reduction half-cell reactions in order. The one with the largest positive reduction potential first ,and tell which is the best oxidizing and reducing agent..

It's important to note that the one easily reduced is the one called a strong oxidizing agent, and the one easily oxidized, is a string reducing agent. (Note that oxidation is taking electrons away from the atom and reduction is giving electrons back).

We are told that C reacts with everything. ...
