Explanation:

Cross - contact occurs when an allergen or contaminant is transferred from one food or surface to another. Washing hands and changing gloves before preparing an allergen - free meal helps prevent the transfer of allergens (if the gloves or hands were previously in contact with allergens) to the new meal. Scraping food off plates (a) is about cleaning dishes, removing pits from fruit (b) is part of food preparation, and cleaning/sanitizing an area after 4 hours (c) is more about general hygiene and time - based cleaning rather than specifically preventing cross - contact for allergen - free meals.

Answer:

d. Washing hands and changing gloves before preparing an allergen - free meal
