Which matched pair is incorrect?
Exosphere — tropospheric clouds
Examining each pair:
(A) Mesosphere — meteors burn: Correct. The mesosphere (~50–85 km altitude) is where most meteors burn up due to friction with denser air.
(B) Stratosphere — ozone layer: Correct. The ozone layer lies in the lower stratosphere (~15–35 km), absorbing harmful UV radiation.
(C) Exosphere — tropospheric clouds: Incorrect. The exosphere is the outermost layer (~600 km upward); clouds ("tropospheric clouds") form in the troposphere, the lowest layer (0–~12 km), not the exosphere. The two layers are at opposite ends of the atmosphere.
(D) Thermosphere — ISS orbit: Correct. The International Space Station orbits at roughly 400 km altitude, which lies within the thermosphere.
Hence the incorrectly matched pair is (C) Exosphere — tropospheric clouds.
