Step-by-step explanation:
1. Colloid
B) Microscopic insoluble particles that are suspended throughout another substance.
Milk is a colloid. It consists of small fat globules suspended in water.
2. Emulsion

Mayonnaise is an emulsion. It consists of oil, egg yolks, vinegar, and seasonings. Normally, the oil and vinegar (95 % water) do not mix. Without the egg yolk , they would quickly separate. Egg yolk contains the emulsifier, lecithin, which is attracted to both oil and water and stabilizes he mixture.
3. Solution
A) A solute that is evenly distributed within the solvent.
Sugar syrup is a solution of sugar in water.
4)Homogeneous
C) A mixture that has its components distributed evenly within the substance.
A homogeneous mixture has only one phase. For example, the sugar syrup is homogeneous, because, even with a powerful microscope, you can't see a boundary between the sugar particles and the water.
