\nStatement A is incorrect; temperature generally increases with height in the stratosphere due to the absorption of UV radiation by the ozone layer. Statement B is incorrect; temperature varies with height in the stratosphere, generally increasing. Statement C is incorrect; temperature decreases, not increases, with height in the troposphere. Statement D is correct; temperature decreases with height in the troposphere at an average rate, known as the lapse rate, which is approximately 6.5 \u00b0C per kilometer. The value 6.4 \u00b0C per kilometer is very close to this average rate and within acceptable variations.

\nThis question tests knowledge of the temperature profiles in the different layers of the Earth’s atmosphere, specifically the troposphere and the stratosphere.

\nThe troposphere is the lowest layer where most weather phenomena occur. The decrease in temperature with height is due to the fact that the troposphere is primarily heated by the Earth’s surface. The stratosphere lies above the troposphere, separated by the tropopause. The increase in temperature in the stratosphere is most pronounced in its upper part where ozone concentration is highest.
