How do passenger oxygen masks deploy on the 737-700?

Explanation:
Passenger oxygen masks on the 737-700 are designed to drop automatically whenever the cabin loses pressurization or climbs to an altitude where supplemental oxygen is needed. A cabin altitude sensor triggers the overhead panels to release the masks, so they fall into place for passengers without any action by the flight crew. Oxygen flow begins when you pull the mask to your face, ensuring you have air immediately. This automatic deployment is why the correct choice is automatic deployment when needed.
