B Correct answer
Explanation

In EJB deployment descriptors, the 'NEVER' transaction attribute explicitly indicates that the method must never be executed within a transaction context. 'NOT_SUPPORTED' allows the method to run outside a transaction but doesn't forbid it if one exists. 'NO_TRANSACTIONS' is not a valid EJB transaction attribute. The default is 'Required' for CMT beans, not empty.
