Which of the following statements about JPA database transaction processing is false?
A) Transaction processing enables a program that interacts with a database to treat a set of operations as a single operation. Such an operation also is known as an atomic operation or a transaction.
B) At the end of a transaction, a decision can be made either to commit the transaction or roll back the transaction.
C) Committing a transaction finalizes the database operation(s); all insertions, updates and deletions performed as part of the transaction cannot be reversed.
D) Rolling back the transaction leaves the database in its state prior to the database operation. This is useful when a portion of a transaction fails to complete properly.

Committing a transaction indeed finalizes the database operation(s) involved, but the statement that all insertions, updates, and deletions cannot be reversed is false. While it's true that committing a transaction applies all changes made during the transaction to the database, this does not mean the changes are irreversible. With proper database backup and logging mechanisms, it's possible to reverse the changes made by a committed transaction, although this might not be straightforward and could require a separate process like restoring from backups or using point-in-time recovery features.
