b, a heterogeneous mixture

Heterogeneous mixture.

Explanation:

Mixture may be defined as the mixing of two or more different substance together. Two different type of mixture are homogenous mixture and heterogeneous mixture.

The heterogeneous mixture does not have uniform composition and forms different layer of mixtures. This mixture can easily pass the light through its solution and shows tyndall effect. The mixture of dirt and water is a heterogenous mixture as it shows all the characteristics of heterogenous mixture.

Thus, the correct answer is option (B).
