Answer: AB

Explanation:

Transactions are units of work that ensure data consistency and integrity by enforcing atomicity, consistency, isolation, and durability (ACID) properties. Spring provides an abstraction layer for transaction management that supports various transaction APIs such as JDBC, JPA, Hibernate, etc.

To use transactions in Spring, we need to do two things:

Enable transaction management by adding @EnableTransactionManagement annotation to a Java configuration class or tx:annotation-driven/ element to an XML configuration file.

Declare transactional boundaries by annotating a class, an interface, or individual methods with the @Transactional annotation. This annotation indicates that the execution of the annotated element should be wrapped in a transaction.
