I am confused on how to balance net ionic equations. I'm wondering if it's similar to redox equations or if there's a different process to it?

Problem:
Balance the net ionic equation

MnO₄^- + I^-  -> I₂ + MnO₂

(basic solution). What is the sum of the coefficients?

Choices:
a)21
b)23
c)29
d)27
e)25

Not sure I started out right for the problem...
Mn⁴⁺ + O₄^- + I^- -> I^2- + Mn⁴⁺ + O₂^2-
O₄^- + I^- -> I^2- + O₂^2-

MnO₄^- is a single ion, you should not split it into atoms. Treat it as a whole.

I₂ is neutral.
