Quiz The correct answer should be model.save( path)

Either the correct answer is not given, or I am missing something. Could someone clarify?

The correct answer is given in the quiz. Your choice is incorrect since it doesn’t make use of your model but looks for model inside tf module.

Well, I think it should be 'model.save(path), but none of the options match.

How about the 3rd option?
Once you’re convinced, please remove the image in the question. Thank you.

I still believe the option is missing.
This is a saved model format : saved model format
While this is a keras model: keras model

The question is not specific about model format. You can save keras models using both APIs.
