A Correct answer
Explanation

Commercial jet aircraft typically fly in the lower stratosphere (approximately 9-12 km altitude) because this layer is stable above weather disturbances in the troposphere. The troposphere has weather and turbulence, while higher layers (mesosphere, thermosphere, exosphere) are too thin for conventional flight.
