   During an ecological survey of the crystalline marshlands on Kepler-186f, an explorer collects three distinct blue liquid samples labeled X, Y, and Z. Sample X allows a focused laser beam to pass through invisibly and exhibits neither sedimentation nor separation after passing through a fine filter. Sample Y displays a luminous, clearly defined light beam when illuminated by the laser, yet its dispersed particles never settle upon standing and pass freely through filter paper. Sample Z quickly separates into a solid sediment layer at the bottom of its vial and is completely clarified when poured through standard filter paper. Based on these observed properties, how are mixtures X, Y, and Z classified?

   • A) Sample X is a colloid, Sample Y is a suspension, and Sample Z is a true solution.
   • B) Sample X is a suspension, Sample Y is a true solution, and Sample Z is a colloid.
   • C) Sample X is a true solution, Sample Y is a colloid, and Sample Z is a suspension.
   • D) Sample X is a true solution, Sample Y is a suspension, and Sample Z is a colloid.
