Step 1: Understanding Exception Handling.
Exception handling begins when an error occurs, leading to an exception being raised. If unhandled, the program terminates; if handled, the exception is processed.
Step 2: Evaluate Each Option.
- Option (A) Program Termination: Occurs if an exception is not caught. - Option (B) Exception is Raised: Happens after an error is detected. - Option (C) Error Occurs in a Program: The initial stage of exception handling. - Option (D) Catching an Exception: Necessary if an exception is raised.
Step 3: Correct Order.
The sequence of events is as follows: 1. An error occurs (C). 2. An exception is raised (B). 3. The exception is caught (D). 4. The program terminates (A) if the exception remains unhandled.
Final Answer: \[\boxed{\text{The correct order is (C), (B), (D), (A).}}\]
