Selected Answer: B
EXPLAIN compiles the SQL statement, but does not execute it, so EXPLAIN does not require a running warehouse. Although EXPLAIN does not consume any compute credits, the compilation of the query does consume Cloud Service credits, just as other metadata operations do. https://docs.snowflake.com/en/sql-reference/sql/explain.html
