Selected Answer: B

No, running REFRESH TABLE customer does not meet the goal of identifying whether maintenance tasks were performed on the Delta table. This Spark SQL command is used to refresh the metadata of a table. It ensures that the latest schema and data are available for queries but does not give any historical information about maintenance operations.
