The answer is

Step-by-step solution

VSEPR Theory

VSEPR theory is the short form for the valence shell electron pair repulsion theory. It can be used to denote the structure of the compounds. To use it, identify the central atom in each compound and the valence electrons on it. The lone pair and bond pair repulsions are considered in determining the structure.

The structure of the compound is shown below.

The structure of the compound is shown below.

The central atom is considered as phosphorus, P. The number of electrons in the valence shell is used for the bond formation. The bonding is satisfied for both phosphorus and oxygen atoms.
