Ah, the classic C++ exception handling question! This one's a breeze - the answer is clearly A. The code creates a custom exception class and throws an instance of it, which the catch block then properly handles and prints the expected message.

I'm not sure, but I think D) Compilation error could also be a possibility if there is an issue with the code.

I agree with Cordelia, because the code defines a custom exception class and throws an object of that class.
