Inserting a Chest tube to a patient

Inserting a chest tube to a patient. A nurse is explaining a chest tube to family members who do not understand where it is placed. What would the nurse tell them?

It is inserted into the space between the lining of the lungs and the ribs.
I don’t exactly know, but I will make sure the doctor comes to explain.
It is inserted directly into the lung itself, connecting to a lung airway.
It is inserted into the peritoneal space and drains into the lungs.
