When an azeotropic mixture of acetone and methanol is distilled, it is not possible to obtain pure acetone or pure methanol through simple distillation. However, it is possible to obtain a solution that has a higher concentration of acetone or methanol than the original mixture.

This is because an azeotropic mixture has a constant boiling point and a constant composition in both the liquid and vapour phases. Therefore, when the mixture is distilled, the vapour that is produced has the same composition as the liquid being distilled. As a result, when the vapour is condensed, it forms a liquid that has the same composition as the original mixture.

However, by using a different distillation technique such as azeotropic distillation or extractive distillation, it is possible to break the azeotrope and obtain a solution with a higher concentration of acetone or methanol. Therefore, option C is the correct answer.
