Option C is correct because Sample Inventory Management includes standard lock behavior for inventory operations based on status. The requirement is to prevent edits after a field sales rep submits inventory records such as transfers and adjustments. Salesforce Help references trigger handlers for Product Batch Item and Product Transfer objects, including ProductTransferLockHandler, which prevents modifications to Product Transfer records when the associated inventory operation is locked. This supports the standard Life Sciences pattern: the Inventory Operation reaches a locked status, and related inventory transaction records can no longer be modified.
Adding finalized status values to the Inventory Operation Locked Status list in Sample Inventory Settings is the appropriate administrative configuration because it tells the system which statuses should make the inventory operation locked. Once the record enters one of those statuses, the standard inventory lock handlers can enforce the restriction.
Option A is not the best answer because a restriction rule controls record visibility, not the complete GxP-style lock behavior for submitted inventory operations and related records. Option B is also not the best answer because a generic flow lock template is not the documented Sample Inventory Settings mechanism for locking inventory operations. Therefore, the consultant should configure the Inventory Operation Locked Status list with the finalized statuses that must prevent further edits.
