C Correct answer
Explanation

EJB transaction attributes control method invocation behavior. 'Never' means the method must NOT be invoked within a transaction context - if a client has an active transaction, the container throws an exception. 'Mandatory' requires a transaction (opposite), 'RequiresNew' always creates a new transaction, and 'Supported' runs with or without a transaction.
