B. Soil and water is a colloid because it consists of minute particles suspended in the medium. Milk is a suspension because it consists of larger particles suspended in the medium, which start to settle when allowed to stand.

C. Soil and water is a colloid because it has a uniform composition. Milk is a suspension because it doesn’t have a uniform composition.

D. Soil and water is a suspension because it consists of larger particles suspended in the medium, which start to settle when allowed to stand. Milk is a colloid because it consists of minute particles that remain suspended in the medium.

E. Soil and water is a suspension because it has a uniform composition. Milk is a colloid because it doesn’t have a uniform composition.
