Solution: Upgrade your license to ArcGIS for Desktop Standard or ArcGIS for Desktop Advanced.

More information: A geodatabase topology requires an ArcGIS for Desktop Standard or ArcGIS for Desktop Advanced license. However, you can build a simple map topology that allows you to edit coincident geometry with an ArcGIS for Desktop Basic license.
