Which of the following is an option when configuring the Output Data Tool for CSV files?

When configuring the Output Data Tool for CSV files, selecting a line ending style is relevant because CSV (Comma-Separated Values) files should support different types of line endings to ensure compatibility across various operating systems. Line endings can differ, such as using Carriage Return (CR), Line Feed (LF), or a combination of both (CRLF). By specifying the line ending style, you ensure that the output file is formatted correctly for the intended platform or usage, preventing issues that might arise when the file is read by different systems.

In contrast, options like spatial index, Excel sheet name, and XML support are irrelevant to CSV files. Spatial index pertains to spatial data types and handling in formats such as shapefiles or spatial databases. Excel sheet name is specific to Excel output formats and is not applicable when creating a CSV file since CSV files do not support multiple sheets. XML support deals with the structure and serialization of XML files, which is also not relevant for CSV formats. Therefore, focusing on line ending style is essential for effective CSV file output.
