An interstellar probe collects glowing gas from the luminescent veil of a dormant orbital beacon and analyzes the emitted light using an onboard spectrometer. Instead of detecting a continuous rainbow, the instrument records four narrow, bright lines separated by broad dark intervals. Which underlying atomic process directly produces this characteristic line emission spectrum?

A) Protons within the atomic nuclei oscillate at resonant frequencies, directly radiating continuous electromagnetic waves as they settle.

B) Excited electrons drop from higher quantized energy levels to lower energy levels, releasing photons with discrete wavelengths.

C) Neutral atoms absorb specific wavelengths from ambient starlight, promoting valence electrons into higher unoccupied shells.

D) Valence electrons overcome attraction and escape completely from parent atoms, converting binding energy into visible light pulses.
