Multiple Choice

When using dry developer, the drying operation is performed

Explanation:
In dry developer use, the surface must be completely dry before applying the developer. After you remove excess penetrant, you dry the surface thoroughly so the dry powder can adhere evenly. Moisture or any residual solvent will cause the powder to clump or smear, hiding or distorting indications. Once the surface is dry, you apply the dry developer and then perform the inspection. So the drying step happens right after removing excess penetrant and before the inspection.
