The throw keyword is used to perform which two actions? (Choose two.)

• A. stop processing of the code
• B. move error handling to a separate thread

* This example throws an ApplicationException exception. Throw New ApplicationException

• B. Break out of the error handler.
• C. Execute code regardless of whether an exception is thrown.

The transfer of control can occur as a result of normal execution, of execution of a break, continue, goto, or return statement, or of propagation of an exception out of the try statement.
