The question's premise is technically inaccurate, as editors in child versions must reconcile to see changes from the default version, regardless of the versioning type. However, interpreting the question's likely intent—to allow other applications or non-versioned users to see changes made to the default version—the correct answer is A. Registering a dataset as traditional versioned with the "move edits to base" option ensures that once edits are posted to the default version, they are written directly to the base business tables. This makes the changes immediately visible to any client or application reading the non-versioned state of the data, without requiring them to access a specific version.

B. Branch versioning is designed for feature service editing workflows and, like traditional versioning, requires a reconcile operation to update a child version with changes from default.

C. Enabling archiving creates a historical log of transactions for auditing or temporal analysis but does not alter the core versioning behavior of isolating edits until reconciliation.

1. Esri ArcGIS Pro Documentation, "Versioning options in ArcGIS Pro": This document explicitly states for the "Register as versioned with the option to move edits to base" setting: "When edits are saved, they are moved from the delta tables to the base tables... Because the edits are in the base tables, the data is accessible to other applications that may not be able to read the delta tables in a geodatabase." (Found under Manage Data > Geodatabases > Traditional versioning > Register data as versioned).

2. Esri ArcGIS Pro Documentation, "A tour of traditional versioning": This guide clarifies the standard workflow: "To merge the changes, you reconcile your version with the default version. This process applies the edits made in the default version to your version." This confirms that reconciliation is the required step for a child version to see parent changes. (Found under Manage Data > Geodatabases > Traditional versioning).

3. Esri ArcGIS Pro Documentation, "Overview of branch versioning": This document describes the branch versioning model, which is based on a service-oriented architecture. The workflow still involves discrete versions that must be reconciled to incorporate changes from other versions, such as default. (Found under Manage Data > Geodatabases > Branch versioning).
