This is your box

You find yourself in a room in the center of that room sits a box. On top of that box written “This is your box”.
To either side of the room are notes attached to the wall. The note to the left reads “Disregard the other note. Inside this box is a baby healthy but sedated around its neck is a steal wire attached to the lid. Any attempt to open the lid will kill the baby. Between the wire and lid is a timer when that time goes off the wire will release and you may open the lid and remove the baby safe and sound. This is your box”.
The note on the other side of the room reads “Disregard the other note. Inside this box is a small bomb strong enough to injure you, scar you, and possibly even kill you. When the timer goes off the bomb will explode. Opening the lid before the timer goes off will disarm the bomb and open the door behind you and you may leave safe and sound. This is your box”
