Which of the following statements about unvalidated range domain attribute data is true?

The statement that unvalidated range domain attribute data can still be saved in the feature class is correct. In geographic information systems, when attribute data is defined with a range domain, it sets limits on the values that the attributes can accept. However, even if the provided attribute values do not adhere to these limits, the data can still be stored in the feature class. This means that GIS systems allow flexibility in data entry, enabling users to input data without immediate validation checks.

While validation processes are essential for maintaining data integrity and ensuring that data meets the specified criteria, the absence of validation does not preclude the data from being saved. This is particularly important in situations where data collection occurs in the field, and immediate validation is not practical. It highlights the idea that data can be incorporated into a system for further review or correction later, thereby supporting workflows in GIS where data accuracy may be progressively improved over time.

In contrast, the other options imply constraints or prohibitions that do not accurately represent the functionality of GIS systems regarding unvalidated data.
