B,C Correct answer
Explanation

When a request arrives for an EJB method, the container performs several preprocessing tasks before invoking the bean: it can start a transaction context if the method requires one, and it checks security credentials to verify the client's authorization. The container does not simply pass requests directly - it provides these middleware services first.
