C is the correct option Explanation : Database Schema Update: Since "Automatically Update Database Schema" is disabled, Appian won't automatically update the database table when you modify the CDT. Manual Update: You need to manually modify the database schema to reflect the new field name ("DATE_OF_ BIRTH"). This ensures consistency between Appian's definition (CDT) and the actual database structure. CDT Update in Appian: After manually updating the database schema, rename the corresponding field within the CDT in Appian to match the new database column name. This step keeps the Appian definition aligned with the database. Data Store Verification and Publishing: Finally, verify and publish the data store in Appian. This process validates the changes made to the CDT against the database schema and ensures Appian can interact with the data correctly.
