Which of the following is a supported data file type for COPY?

Explanation:
Understanding what file formats COPY supports is key. JSON is a native data format that Snowflake can parse directly during a COPY operation, loading into the VARIANT data type and preserving nested structures. This makes JSON a natural and straightforward choice for loading semi-structured data with COPY. The other options aren’t standard built-in formats recognized by COPY for direct loading: YAML and PDF aren’t supported as file formats for COPY, and TXT would require a custom text file format and delimiter rules rather than being a native, out-of-the-box data format.
