Answer: Balanced net ionic equation is 
Explanation:
Neutralization is a chemical reaction in which an acid and a base reacts to form salt and water.
Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.
The given chemical equation is:

The ions which are present on both the sides of the equation are sodium and phosphate ions and hence are not involved in net ionic equation is:
