An OmniStudio Developer needs to create a FlexCard that aggregates data from three different Salesforce...

When testing a FlexCard data source in the designer, the developer must provide valid runtime values for context variables so the configured Integration Procedure can execute as it would at runtime. In this scenario, that means manually entering a valid Context ID, such as an Account record ID, in the Setup or Test Data Source settings and then viewing the returned data. Without a valid context value, the Integration Procedure may not receive the input required to query Account, Opportunity, and Case data. Option C is important inside the Integration Procedure design, but the question asks about testing the FlexCard’s data configuration in the designer. Option B is not generally required for SOQL. Option D is a design choice, not the key testing step.
