"Polar ionic" is the nature of the P-O bond among the choices given in the question that is present in phosphorus pentoxide (P2O5). The correct option among all the options that are given in the question is the last option or option "E". I hope that this is the answer that has come to your help.
PBCHEM
Correct Answer: option B. moderately polar covalent 

Reason: 
Both phosphorus and oxygen are non-metals, and hence they are bonded by covalent bonds. Furthermore, the electro negativity of P and O is 2.1 and 3.5 respectively. The difference in electro negativity is 1.4. Due to the difference in electro negativity, nature of the P-O bond in phosphorus pentoxide (P2O5) is moderately polar covalent.
