Explanation:

Step1: Understand the concept of mixtures and filtration

A mixture is a combination of two or more substances. Filtration is a method to separate solids from liquids.

Step2: Analyze each option

• Salt water: Salt is dissolved in water. The salt particles are too small to be separated by filtration.
• Skimmed milk: It is a colloid. The particles are too small to be separated by filtration.
• Orange juice with pulp: The pulp is a solid that can be separated from the liquid juice by filtration.
• Distilled water: It is a pure substance, not a mixture.

C. orange juice with pulp
