A student conducts tests on three unlabeled liquid mixtures, designated X, Y, and Z, to determine their mixture classifications. Mixture X is slightly cloudy, remains stable without settling over time, and clearly scatters a narrow beam of red laser light directed through it. Mixture Y is completely transparent, passes entirely through standard filter paper without leaving residue, and shows no visible path when illuminated by the laser beam. Mixture Z initially appears opaque, separates into distinct layers after resting undisturbed for thirty minutes, and leaves solid particles on the filter paper upon filtration. Based on these experimental observations, which option correctly identifies the three mixtures?
