D. The table contains only the current active rows

Answer: B

Explanation:

In a system-period temporal table, every row has a pair of timestamps, which are set by the DB2 system and recorded in the begin_column and end_column columns. DB2 uses the SYSTEM_TIME period to audit the data changes. It provides the application with the database managed row begin and row end timestamp maintenance, providing non-overlapping time periods with no gaps in time.
