C. Using the System.Limit class to monitor the current CPU governor limit consumption can indeed help you keep track of your governor limits during execution. It's a valuable debugging and monitoring technique. D. Using the Database.Savepoint method to enforce database integrity is a valid approach to ensuring data consistency and integrity within a transaction. Savepoints allow you to set points within your transaction and roll back to those points if necessary.
