The correct answer is the second statement, "Οκ,πάμε να πας κ εσύ να ξεκουραστείς." This statement is a response to the first statement, "Μπορείς αν θέλεις να έρθεις σπίτι μου να κοιμηθείς." The second statement suggests going somewhere to rest, indicating that the person being spoken to can come along and rest as well. The third statement, "Πάμε για ποτό μωρέ και ξεκουράζεσαι αύριο," suggests going for a drink instead of resting, which is not a response to the first statement.
