Answer: SINGLE=FALSE

The question asks for the correct COPY INTO SQL command syntax to unload data into multiple files. According to Snowflake documentation and the community discussion, the COPY INTO command uses the SINGLE parameter to control whether data is unloaded into a single file or multiple files. The default value is SINGLE = FALSE, which means data is unloaded into multiple files. All community comments with upvotes (including the highest upvoted comment with 12 upvotes) confirm that SINGLE = FALSE is the correct syntax for unloading into multiple files. Options A (SINGLE=TRUE) and C (MULTIPLE=FALSE) would unload into a single file, while option B (MULTIPLE=TRUE) is not a valid parameter in Snowflake's COPY INTO syntax.
