Why do aircraft generally prefer flying in the lower stratosphere?
Answer and explanation
Correct answer: Weather turbulence is relatively less there
Option A is correct because the stratosphere is relatively stable: temperature generally increases with height, which reduces strong vertical convection and mixing. Since most clouds, storms, and vigorous turbulence develop in the troposphere, aircraft cruising near the lower stratosphere can often experience smoother conditions and lower drag. This is a general preference, not an absolute rule. Rainfall is not highest there, oxygen is not most concentrated there, and cloud formation is not compulsory, so B, C, and D are incorrect.
