The correct option is Blood.EXPLANATION:A mixture is a combination or solution of two or more substances that are not chemically united or bonded to each other.1) Homogeneous Mixture: A homogeneous mixture is one whose composition is uniform throughout the mixture.It is the type of mixture where components are distributed uniformly.Examples of homogeneous mixtures are Air, Sugar, water, Rainwater, Vinegar, Dishwashing detergent, Steel, Cup of Coffee, Detergent, Cologne, Beverages, Alloys, etc. 2) Heterogeneous Mixture: Materials that are insoluble in a solvent and have particles that are visible to naked eyes form a suspension. A suspension is a heterogeneous mixture.A heterogeneous mixture can be easily separated by just gravity or by applying normal physical processes like centrifugal or density difference.Colloids are heterogeneous mixtures in which the particle size is too small to be seen with the naked eye, but is big enough to scatter light. The particles are called the dispersed phase and the medium in which they are distributed is called the dispersion medium.Examples of the heterogeneous mixture are Soil, Blood, Fog, Smog, Smoke, Clouds, Sand and Water, and Blood.
