Required --------- The Container must invoke an enterprise Bean method whose transaction attribute is set to Required with a valid transaction context. If a client invokes the enterprise Bean�s method while the client is associated with a transaction context,the container invokes the enterprise Bean�s method in the client�s transaction context. If the client invokes the enterprise Bean�s method while the client is not associated with a transaction context, the container automatically starts a new transaction before delegating a method call to the enterprise Bean business method.
Option A which indicates that method 2 does not run in a txn context violates this.
