Which of the following can enhance the above argument? ['The restaurant stipulates that when ordering Cantonese cuisine, you cannot order Sichuan cuisine, and vice versa.', 'The restaurant stipulates that if you order Sichuan food, you can not order Cantonese food, but if you order Cantonese food, you must order Sichuan food.', 'Mr. Zhang is from Sichuan and only likes Sichuan cuisine.', 'Mr. Zhang is Cantonese, but he does not like Cantonese food.']
