This approach allows the company to have a separate business unit for each B2C Commerce storefront, which provides data segregation and customization for each market. Each business unit can have its own Marketing Cloud product catalog, which is a data extension that contains product information for generating product recommendations using Einstein. D. This approach allows the company to implement abandoned cart using Marketing Cloud's Behavioral Trigger feature, which can track customer behavior on the B2C Commerce storefront and trigger an email journey based on predefined rules. The abandonment journey can include product recommendations based on the products left in the cart. The B2C Commerce storefront must also be extended to re-create the customer's shopping cart with abandoned products using a link or button in the email.
