As shown in Figure 4, the temperature measured by a meteorological observation station changes with altitude, and the weather changes near this meteorological observation station mainly occur in the following altitude range. A

Generally speaking, the troposphere temperature decreases with height, while the stratosphere is the opposite.

At the tropopause, the temperature level remains constant with altitude, which is exactly at 10 km. So 10km can be regarded as the tropopause.

The weather change is mainly caused by the change of troposphere atmosphere, so choose a.
