A developer is designing a logging system with a base class 'Logger' that has a 'log' method. They want to create a 'FileLogger' subclass that writes to a file, and a 'ConsoleLogger' subclass that prints to the console. Both subclasses should be usable interchangeably through the base class interface. Which design best achieves this?

Define 'log' only in the base class and use a conditional to write to file or console based on an attribute.

Create separate, unrelated classes for file and console logging with no common base.

Define 'log' in each subclass with different method names, and use type checking to call the appropriate method.

Define 'log' in the base class as a placeholder that raises NotImplementedError, and override it in each subclass.
