In liquid penetrant testing, which step follows penetrant dwell time to reveal indications?

Explanation:
Development with wet developer is the step that reveals indications. After penetrant has dwelled, you remove surface penetrant and prepare the area (usually by rinsing and drying). The developer then draws penetrant out of any defects and concentrates it at the surface, creating visible (or fluorescent) indications that show where flaws are. Rinsing and drying are preparatory/removal steps and do not by themselves reveal indications, while emulsification is a removal method for emulsifiable penetrants, not the reveal step.
