Answer:

The correct answer is option A.

Step-by-step explanation:


6Ca+4PO_4\rightarrow 2Ca_3(PO_4)_2

Number of molecules of
Ca_3(PO_4)_2 =2

In 1 molecule
Ca_3(PO_4)_2 , there are 8 oxygen atoms:


4* 2 = 8oxygen atoms.

Then 2 molecules of
Ca_3(PO_4)_2 :


2* 8 = 16 oxygen atoms.

Hence, the correct answer is option A.
