Step-by-step explanation:

An atom is nuetral when the number of protons is equal to the number of electrons.

Electrons and protons have the same but opposite charge which is 1.6 × 10^-19.

So since they have the same charge they need an equal number of protons and electrons in the atom for it to be nuetral.

So it is A
