• A. Suspension
• B. Alloy
• C. Colloid
• D. Solution

Answer: (C)

Colloids are mixtures where tiny particles are dispersed through a medium and stay suspended rather than settling out. Milk is an emulsion, a type of colloid, with fat droplets dispersed in water. The particles are larger than those in a true solution but too small to settle quickly, and they scatter light, giving the milky appearance. This distinguishes colloids from suspensions, where larger particles eventually settle, and from solutions, where particles are dissolved at the molecular level and the mixture is uniform and clear.
