a. the substances are dissolved in the mixture.
b. the substances are evenly mixed throughout.
c. the mixture is made up of different consistencies.
d. the mixture is made up of a single consistency.

C. The mixture is made up of different consistencies.

Explanation:

A heterogenous mixture is substance constituted by two or more pure substances (elements or compounds) in any proportion, where each pure substance keeps its individual properties, the mixture does not have uniform properties, and each pure substance remains separated, in different phases, which is what the term consistencies means.

Some examples of heterogeneous mixtrures are: sand and water, oil and water.

For better visualization think on this: i) pure water is a pure substance (a compound with definite composition), ii) sea water is a homogeneous mixture (sal and water keep their individual properties, may be in any proportion one respect each other, and are intimimated mixed forming a solution), and iii) water with sand form a heterogeneous mixture (you can observe clearly two phases).
