<u>Answer:</u> The correct answer is Option C.
<u>Explanation:</u>
We are given some polyatomic ions with their oxidation states. Polyatomic ions are defined as the ions which are formed from more than 2 atoms.
We need to find out the chemical formula for ammonium phosphate.
For this, the polyatomic ions used are:
Ammonium ion - 
Phosphate ion - 
By using criss-cross method, the oxidation state of the ions are exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.
Thus, the chemical formula for this compound is 
Hence, the correct answer is Option C.
