Solution
The correct option is C Ink will give the spots along with the substance
The components present in the ink of the pen will be separated upon being dissolved by the solvent. The chromatogram obtained eventually will contain a mixture of spots that include both the components of ink from the pen and the dye. Thus, the accuracy of the analysis ofthe sample of dye is affected.
