Final answer:
The correct answer is A. le.
Step-by-step explanation:
The correct answer is A. le. In Spanish, when expressing likes and dislikes, we use the verb 'gustar' followed by an indirect object pronoun. In this case, 'las enchiladas' is the subject and 'a mi amigo' is the indirect object. The correct pronoun to use for 'a mi amigo' is 'le'.
