A retail store wants an application to process a new customer loyalty account.

In the context of creating a customer loyalty account where the customer's contact information is captured and displayed within the case, organizing and relating this data efficiently is key.

B. An Embedded data field: This option allows the contact information (name, email, phone number, address) to be structured as part of the case data in a coherent and integrated manner. Embedding this information ensures it is directly associated with each loyalty account case, facilitating data management and access within the application's data model.

A Data reference field (A) links to data instances outside the case, which is not the primary requirement here. A Case reference field (C) is used for linking cases together, which does not apply to this scenario of capturing contact information. A Query field (D) is intended for retrieving data based on a query, which is not relevant for directly embedding and displaying entered contact information within a case.
