Which matched pair is incorrect?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Exosphere - tropospheric clouds.
The Exosphere is the outermost layer of Earth's atmosphere, starting at about 700 km and extending into space. It contains extremely thin air where atoms can escape into the vacuum. In contrast, tropospheric clouds (weather phenomena) are strictly limited to the Troposphere, the lowest layer (0–12 km), where 99% of the atmosphere's water vapor resides. The Exosphere is far too high and thin for cloud formation, making this pairing scientifically inaccurate and physically impossible.
The other given options are matched correctly.
