DocuSign. This answer fits because the requirement is about the specific platform mechanism named in the option, not a nearby workaround.

The Core Concept Explained: Document automation reduces manual review by turning files into governed records, checklist items, extracted fields, or signature events. The design must preserve traceability from upload through review.

Step-by-Step Technical Analysis: Separate document intake from record processing. Configure the document type, checklist, extraction, signature, or IDA/IFR behavior, map the captured values to the application record, and test with real sample files. Confirm exception handling for unreadable documents, missing uploads, and resubmission cycles. Use the DocuSign integration supported by the Public Sector toolkit.

Why the Incorrect Options Are Wrong: B may look related, but it does not place the logic in the correct declarative Public Sector or OmniStudio configuration layer. C may look related, but it does not place the logic in the correct declarative Public Sector or OmniStudio configuration layer. D may look related, but it does not place the logic in the correct declarative Public Sector or OmniStudio configuration layer.
