In equipment specifications, the oxygen duration for passenger generators is given as which of the following minutes?

Explanation:
Oxygen duration is the amount of time the onboard oxygen supply will keep delivering oxygen to passengers at the standard flow rate. It depends on how much oxygen is stored and how fast it’s being used. For passenger oxygen generators, the specification is commonly 13 minutes, which reflects a typical design choice that provides enough time for a safe descent and crew actions without adding unnecessary weight or complexity. The other numbers would imply a smaller or larger system than what is usually certified for standard passenger oxygen, so they don’t fit the common spec.
