A stellar astrochemist calibrates an automated spectrometer to detect atomic emission lines from ions excited to the fourth principal energy level ($n = 4$). To program the detection filters correctly, she must verify the types of sublevels available in this shell and the maximum number of electrons it can theoretically accommodate. Which statement correctly identifies the sublevel composition and total electron capacity of the $n = 4$ principal energy level?

A) It contains only $s$, $p$, and $d$ sublevels, holding a maximum of 18 electrons.

B) It contains $s$, $p$, $d$, and $f$ sublevels, holding a maximum of 16 electrons.

C) It contains $s$, $p$, $d$, and $f$ sublevels, holding a maximum of 32 electrons.

D) It contains $s$, $p$, $d$, $f$, and $g$ sublevels, holding a maximum of 50 electrons.
