Answer: b. Chromatography

Explanation:

Chromatography procedure will be used to separate the pigments in the ink.

To carry out this procedure, a small ink-dot is placed at the end of a filter paper. This ink-dotted end of the filter paper is then placed in a solvent.

As the solvent moves up the filter paper, it dissolves the ink mixture and spreads its component pigment across the paper.
