Respuesta :
The correct option is "I am an American-born Korean who loves Mexican food." since it uses capital letters when referring to nationalities.
The capitalization rules indicates that nationalities are proper nouns so they should always be in capital letters.
In this case, the words that should be capitalized in the sentence are: American, Korean and Mexican.
Options A and D are incorrect since not all words mentioned before are capitalized. And option C is also incorrect since the word "born" should not be capitalized.
