Select correct balanced net ionic equation

Select the correct balanced net ionic equation for each of the following reactions, occuring in aqueous solution. Input the associated letter labels, in order (i)-(iii), no spaces, no commas. e.g. GBF

(i) 2HCl + Mg --> H2 + MgCl2
(ii) CuSO4 + CaCl2 --> CuCl2 + CaSO4
(iii) Cu(NO3)2 + Ni --> Cu + Ni(NO3)2

A. CuSO4 + Ca2+ --> Cu2+ + CaSO4
B. Mg + 2HCl --> Mg2+ + 2Cl- + H2
C. Cu2+ + Ni --> Cu + Ni2+
D. Ni + Cu2+ + 2NO3- --> Ni(NO3)2 + Cu
E. Ni + Cu2+ + 2NO3- --> Ni2+ + Cu + 2NO3-
F. Mg2+ + 2Cl- --> MgCl2
G. CaCl2 + Cu2+ --> Ca2+ + CuCl2
H. 2Cl- + Cu2+ --> CuCl2
I. Cu(NO3)2 + Ni --> Cu + Ni(NO3)2
J. 2H+ + Mg --> H2 + Mg2+
K. SO42- + Ca2+ --> CaSO4
L. none of the above
