For their campaign targeting strategy, Márcia wants to limit the products contained in "gourmet candies." How can they limit the products in this category?

The correct answer is With the refine button because the refine button allows Márcia to narrow down the product selection within the "gourmet candies" category by applying specific filters. These filters can help focus on particular types of products, such as specific subcategories, price ranges, or ratings, effectively limiting the scope of products being targeted in the campaign. This tool is particularly useful for refining targeting criteria and ensuring that the ad reaches the most relevant audience. The target menu and number slider do not offer the same level of granularity for filtering products within a specific category like the refine button does.
