Which represents the balanced equation for the beta minus emission of phosphorus- 32 ?

In beta minus emission, a neutron changes into a proton and an electron is emitted. The mass number stays 32, while the atomic number increases from 15 to 16. Thus phosphorus-32 becomes sulfur-32 and emits an electron, which is written as ³²₁₆S + ⁰₋₁e; this is choice C.
