Answer:
The answer will be the third one, sé.
___________
Step-by-step explanation:
Yo se llegar al aeropuerto. (English) I know the way to the airport. The first one ‘sabo, means I know, but it's past tense therefore it wouldn’t be the answer. Conozco also means I know but it’s when you know a place but in this case is more going to the airport so it wouldn’t be the answer. Conoco isn’t a word in Spanish, which is probably a typo. Finally, sé it’s when you know something in present form therefore that’s the answer the question.
