Which button is used to fill in attribute names in the AttributeManager dialog?

• A. Import button
• B. Export button
• C. Fill button
• D. Auto-detect

Answer: (A)

Import is used to populate the AttributeManager with a predefined list of attribute names by loading them from an external file. This lets you quickly bring in a known schema so the grid is filled with the exact attribute names you expect, without typing them manually. The other options serve different purposes: Export saves the current mappings to a file, Auto-detect tries to infer mappings automatically, and Fill typically populates values within the mapping rather than bringing in a new set of attribute names.
