In OmniStudio, the Edit Block element is purpose-built for allowing users to dynamically add, edit, or delete rows of related data, such as dependents under a policy. To save these changes, Remote Actions (typically backed by Apex or API) are used to process each record operation (Create/Update/Delete).

A. Use an Edit Block element configured with Remote Actions – Correct. This is the recommended and most scalable way to support CRUD operations in OmniScripts for collections (e.g., dependents). The Edit Block provides UI-level support, while Remote Actions handle back-end interaction with Salesforce or external systems.

Incorrect Options:

B. Text Block is for display purposes and cannot manage data input or backend actions.

C. Input Block elements do not support row-level add/edit/delete functionality as Edit Blocks do.

D. SOQL is a read-only query language and cannot be used to update or delete records directly within an OmniScript.
