Selected Answer: B
The EXPLAIN statement in Spark SQL is used to display the execution plan of a query. This plan shows how Spark will execute the query, including details about the operations and stages involved. While it is useful for understanding and optimizing query performance, it does not provide historical information about maintenance tasks like optimization, compaction, or vacuuming performed on the table.
