   While navigating the shimmering auroral cloud of an uncharted crystalline moon, the exploration drone Astraea traps an isolated particle from the ionized plasma. Sensor telemetry reveals that this monoatomic species possesses an atomic number of 15, a mass number of 31, and a net electrical charge of $-3$. Based on these spectral readings, which set of subatomic particles correctly constitutes this captured entity and defines its ionic classification?

   • A) 15 protons, 16 neutrons, and 12 electrons, classifying it as a cation.
   • B) 18 protons, 13 neutrons, and 15 electrons, classifying it as an anion.
   • C) 15 protons, 31 neutrons, and 18 electrons, classifying it as an anion.
   • D) 15 protons, 16 neutrons, and 18 electrons, classifying it as an anion.
