A Marketing Cloud Next Consultant wants to build an audience flow to send a promotional...

The most appropriate pattern is Get Records followed by Decision . The flow needs information from a related CRM object—the Case object—that isn't inherently part of the current audience-flow record. A Get Records element can retrieve a matching Case for the customer using criteria such as Contact ID and an open Case status. The subsequent Decision element evaluates whether an open Case was returned and routes the customer accordingly.

Customers with an open case can be diverted away from the Send Email Message path, while those without a matching open Case proceed through the promotional sequence. This structure keeps the suppression condition explicit and maintainable within the flow.

An "Exclusion Filter" isn't the standard Flow Builder element presented for this type of CRM-record lookup and routing. A Decision element alone also can't simply assume access to arbitrary related Case data; the related records first need to be retrieved or otherwise supplied to the flow.

Salesforce lists both Get Records and Decision as supported Flow Builder elements for marketing automation. The supplied master bank likewise keys option A.
