The correct answer is option 2, i.e. atmosphere.
Context: The sentence is talking about greenhouse gases increasing due to global forest loss. Greenhouse gases are present in a particular layer around the Earth.
Meaning of the words:
-
Thermosphere – A very high layer of Earth’s atmosphere, not commonly referred to in general environmental discussions.
-
Atmosphere – The layer of gases surrounding the Earth where greenhouse gases collect.

Microsphere – A scientific term unrelated to Earth's natural systems in this context.

Reason: The line says – "Global forest loss also leads to more greenhouse gases in the (3)______." The atmosphere is where greenhouse gases cause the greenhouse effect and contribute to global warming.
Final Sentence: Global forest loss also leads to more greenhouse gases in the atmosphere.
Hence, the chosen option is correct.
