Correct Answer: 5
Explanation: BATCH
Combines multiple DML statements to achieve atomicity and isolation when targeting a single partition or only atomicity when targeting multiple partitions. A batch applies all DMLs within a single partition before the data is available, ensuring atomicity and isolation. For multiple partition batches, logging can ensure that all DMLs are applied before data is available (isolation), while atomicity is achieved per partition.
