During a laboratory investigation, a mass spectrometer identifies an ion with a net charge of $-1$. Subsequent nuclear analysis indicates that the ion has an atomic number of 17 and a mass number of 37. Based on this information, which statement correctly identifies the subatomic composition and distribution of this ion?

A) The ion has 17 neutrons within its nucleus and 16 electrons arranged outside the nucleus.

B) The ion has 20 neutrons within its nucleus and 16 electrons arranged outside the nucleus.

C) The ion has 20 neutrons within its nucleus and 18 electrons arranged outside the nucleus.

D) The ion has 37 neutrons within its nucleus and 18 electrons arranged outside the nucleus.
