net ionic equations chemistry?

I can't seem to get the right answer. I think my answers are right but the key says no! help...

Select the correct balanced net ionic equation
for each of the following reactions, occuring
in aqueous solution.

1) CuSO4 + CaCl2 CuCl2 + CaSO4
2) H3PO4 + 3NaOH 3H2O + Na3PO4
3) K2CO3 + Ca(NO3)2 2KNO3 + CaCO3

A. CuSO4 + Ca2+ Cu2+ + CaSO4
B. PO43- + 3NaOH Na3PO4 + 3OH-
C. K2CO3 + Ca2+ 2K+ + CaCO3
D. 3OH- + 3H+ 3H2O
E. CO32- + Ca2+ CaCO3
F. Ca(NO3)2 + 2K+ Ca2+ + 2KNO3
G. CaCl2 + Cu2+ Ca2+ + CuCl2
H. 2Cl- + Cu2+ CuCl2
I. 2NO3- + 2K+ 2KNO3
J. SO42- + Ca2+ CaSO4
K. 3Na+ + PO43- Na3PO4
L. none of the above
