B Correct answer
Explanation

Phosphenes are the luminous sensations of stars, colors, and patterns you see when you apply mechanical pressure to your eyes or rub them. This occurs because pressure stimulates the retinal cells, which your brain interprets as light signals even though no actual light is entering the eye. The other terms (racines, coloroscenes, chloroscenes) are not real scientific terms.
