Which requirement must be met before an Administrator can perform a search index?

Before performing a search index in Salesforce B2B Commerce, it is crucial that at least one product has aProductCode assigned (D). The ProductCode is a unique identifier for products in Salesforce B2B Commerce, and it is essential for indexing and searching products within the platform. While images (A) and SKUs (B) enhance product listings and navigation, they are not prerequisites for indexing. Ensuring products are marked as Active (C) is important for them to appear in search results, but the presence of a ProductCode is fundamental to the indexing process itself.
