In which part of the atmostphere is the civilian aircraft usually flying?

Question

To tackle the question, I’ll examine what each atmospheric layer is generally associated with and relate it to typical flight operations.
Option a: Mesosphere. This layer lies well above where most aircraft cruise. It is where meteors burn up and is far higher than commercial flight levels, so it cannot be the usual cruising region for civilian airliners.
Option b: Thermosphere. Even higher than the mesosphere, the thermosphere is where the International Space Station orbits and where extreme solar effects occur. Civilian aircraft do not fly in this layer due to lack of air density and the appropriate flight environment.
Option c: Stratosphere. This layer starts above the troposphere and contains the ozone layer. Commercial airliners typically cruise at altitudes around 30,000 to 40,000 feet (roughly 9–12 km), which places them in the upper troposphere and lower stratosphere. This region offers stable air and lower turbulence compared to the troposphere, making it the conventional cruising domain for many civilian flights.
Option d: Exosphere. This is the outermost atmospheric layer where particles are sparse and essentially merge into space. It is far beyond typical aviation altitudes, so it’s not where civilian aircraft operate.
Putting it together, the most accurate choice is that civilian aircraft usually fly in the stratosphere, given that modern jet routes commonly reach into the upper troposphere and lower stratosphere for efficient cruising conditions. The other layers are either too low and turbulent (troposphere, where weather occurs) or too high and thin for safe, practical aviation.
