A developer is reviewing a colleague's code that contains the line `raise ArithmeticError("calculation failed")`. The developer knows that ArithmeticError is an abstract base class. What is the most accurate statement about this code?

It will raise an ArithmeticError, but it is better practice to raise a specific subclass like ZeroDivisionError.

It will raise a RuntimeError because ArithmeticError is not meant to be raised directly.

It will raise a ValueError because the message is not a valid error code.

It will raise a TypeError because abstract classes cannot be instantiated.

Which built-in exceptions are NOT subclasses of the Exception class?

SystemExit and KeyboardInterrupt

ZeroDivisionError and OverflowError

A developer is building a monitoring tool that must log every exception that occurs, including SystemExit and KeyboardInterrupt, but must then re-raise the exception so the program's normal termination behavior is preserved. Which except clause should be used?

except SystemExit, KeyboardInterrupt:

except (SystemExit, KeyboardInterrupt):
