Answer: INCLUDE_QUERY_ID

The INCLUDE_QUERY_ID copy option includes the query ID (which is a UUID) in the names of unloaded files. This helps uniquely identify files generated by specific COPY operations. VALIDATION_MODE is used for validating data without loading, SINGLE specifies output to a single file, and HEADER includes column headers in the output - none of these options include UUIDs in file names. The community discussion with 100% consensus on option D and reference to Snowflake documentation confirms this is the correct answer.
