Answer:

[tex]\boxed {\tt A. \ 2 \ phosphorus \ and \ 5 \ oxygen}[/tex]

Explanation:

We are given the chemical formula:

[tex]\sf P_2O_5[/tex]

The subscript of 2 comes after the P. The element P is phosphorous, so there are 2 phosphorous atoms.

The subscript of 5 comes after the O. The element O is oxygen, so there are also 5 oxygen atoms.

Therefore the correct answer is A. 2 phosphorous and 5 oxygen
