The symbol for a species is determined by the number of protons it has, which is also known as its atomic number. This is because the number of protons defines the element.

In this case, the species has 15 protons. If you look at the periodic table, the element with 15 protons is Phosphorus, which has the symbol P.

The number of neutrons is used to determine the isotope of the element. The total number of protons and neutrons together is known as the mass number. In this case, 15 protons + 16 neutrons = 31.

The number of electrons determines the charge of the species. If there are more electrons than protons, the species is negatively charged. In this case, there are 18 electrons and 15 protons, so the species has a charge of -3.

So, the symbol for a species that contains 15 protons, 16 neutrons and 18 electrons is 31 15 P^3-.

Therefore, the correct answer is D. 31 15 P^3-.
