Correct answer
Explanation
Enterprise JavaBeans (EJB) specification defines exactly three types of beans. Session beans encapsulate business logic and workflow. Entity beans represent persistent business data (now largely replaced by JPA entities). Message-driven beans handle asynchronous messaging via JMS. 'Object bean' is not a standard EJB type.
AI explanation
Enterprise JavaBeans historically come in three types: Session beans (handle business logic for a client), Entity beans (represent persistent data), and Message-Driven beans (process asynchronous JMS messages). 'Object bean' is not a recognized EJB category, which is why it's excluded.
