Oxidation and reduction - arranging reactions in order
I am having trouble with this question:

i) A reacts spontaneously with 1 mol/L BNO3, 1 mol/L D(NO3)2 and dilute sulfuric acid. A does not react with 1 mol/L C(NO3)2

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

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

iv) D reacts spontaneously with 1 mol/L BNO3. 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 listed first.

A2 + 2e- A(s)
B+ + e- B(s)
C2+ + 2e- C(s)
D2+ + 2e- D(s)
2H+ + 2e- H2(g)
