Final answer:
Without specific context, it's difficult to provide a precise answer to which feature can be used to revert normalization on a model. Reversion of normalization, if supported by a system, would be clearly documented. General knowledge suggests that normalization is often irreversible, but some systems may offer rollback features.
Step-by-step explanation:
The feature to revert any normalization that has occurred on a model within a system is typically a functionality provided by the system's data management tools.
However, the question seems to be very specific, and without a clear context of which system or software is being discussed, it's hard to determine an accurate answer. In many systems, normalization processes are irreversible once they are applied, as they often involve complex data transformations and database restructuring. Some environments might offer a feature to rollback changes or undo certain operations, often referred to as a rollback feature or a versioning system.
If we're discussing a specific software that includes features mentioned in the options like 'Undo Normalization Scheduled Job', 'Rollback Normalization Business Rule', or 'Revert Normalization UI Action', the correct feature would be provided by the software's documentation or support resources. In a general sense, if a software system allows reversal of data normalization, it usually provides a clear mechanism or function to do so.
