If an aggregate fetches Orders and their reviewers, which of the following options is true?

The statement that the aggregate returns Orders with Priority and with zero or more Employees is true because aggregates in OutSystems are designed to fetch data from related entities based on defined relationships. In the scenario where Orders are associated with Employees (reviewers, in this context), the aggregate can indeed include those relationships.

It is acceptable for an order to be fetched with zero or more associated employees, reflecting scenarios where some orders may not have any reviewers, while others might have multiple. The addition of the Priority field enhances the detail of the data being fetched by the aggregate. This relationship in the data model allows for flexibility in how orders and their reviewers are represented, ensuring that all relevant data can be accessed together in a single query, which is the core capability of aggregates in the OutSystems platform.

The context of the other options indicates limitations that are not aligned with the functionality of aggregates, reinforcing why the chosen statement accurately describes the capabilities of an aggregate in this instance.
