Solution
The correct option is C usually diffuses into the interior of a fiber from a water solution. A dye is a colored substance that has an affinity to the substrate to which it is being applied. The dye is generally applied in an aqueous solution and may require a mordant to improve the fastness of the dye on the fiber. Hence option C is correct.
