Answer: (D)

In solvent removers (Method C), the aim is to remove penetrant residue without spreading it. Start with a dry wipe using a clean, lint-free cloth in a single direction to lift the bulk of the penetrant and any surface contaminants. Then use a fresh cloth lightly moistened with solvent to remove any remaining penetrant, again wiping in one direction only. Do not rub back and forth, and fold or replace the cloth so you always have a clean surface for each wipe. Inspect the cloth as you go and continue with fresh cloths until little or no penetrant remains. This sequence minimizes smear, prevents recontamination, and ensures an accurate indication.
