Explanation:
According to the Product Variations and Attributes page, product variations and attributes are features that allow you to create and manage products that have different versions or options, such as size, color, style, etc. Product variations and attributes can be set up using the B2B Commerce app navigation menu in two places: Products and Product Workspace. Products option allows you to access the product list view, where you can create, edit, delete, clone, or import/export products. Product Workspace option allows you to access the product workspace, where you can view and edit product details, such as name, description, status, visibility, category, image, etc. You can also add product variations and attributes in the product workspace by using the Variation Grouping tab or the Guided Setup tab. Therefore, options A and D are correct. Options B, C, and E are false because Commerce Setup, Entitlement Policies, and Catalogs are not places where you can set up product variations and attributes using the B2B Commerce app navigation menu. Commerce Setup option allows you to install components for your B2B Commerce site, such as reports, dashboards, sample data, etc. Entitlement Policies option allows you to manage entitlement policies for your B2B Commerce site, such as minimum order quantity, maximum order quantity, reorder frequency, etc. Catalogs option allows you to manage catalogs and catalog assignments for your B2B Commerce site. Catalogs are collections of products that are available for a store or a reorder portal.
