FINAL ANSWER:
Wo wohnst du
Step-by-step explanation:
In the given conversation between Jan and Finn, they are engaging in an informal exchange, as indicated by their use of "Hallo" and "Wie geht es dir?" which are informal greetings. Therefore, the correct phrase to complete the conversation is "Wo wohnst du?"
This phrase means "Where do you live?" and is in the informal second person singular form, matching the informal tone of the conversation. "Wo hast du gewohnt" is in the past tense and would not be appropriate in this context. "Wo wohnen Sie" and "Wo wohnen sie" use formal language, which is not consistent with the informal tone of the conversation between Jan and Finn.
