Correct Option (c) Mixtures have a fixed composition.

Option (c) is not true regarding mixtures. Mixtures are composed of two or more pure substances, such as elements or compounds, that are physically combined. Unlike pure substances, mixtures have a variable composition, which means that the proportion of the components can be varied. Mixtures can be separated by physical means, such as filtration, distillation, or chromatography.

Furthermore, mixtures do not have a definite set of properties, as their properties can vary depending on the proportion of the components. In contrast, pure substances have a fixed composition and a set of characteristic properties that are unique to them. Therefore, the correct answer is option (c) Mixtures have a fixed composition.
