Correct option is C

• The biosphere is a delicate balance of different ecosystems that sustain life through processes like energy flow, nutrient cycling, and the interactions between organisms and their environment.

• Atmosphere: The layer of gases surrounding Earth, which is essential for life but is not itself the area where life is sustained.
• Troposphere: The lowest layer of Earth's atmosphere, where weather and life occur, but the biosphere extends beyond just the troposphere.
• Stratosphere: The layer above the troposphere, where the ozone layer is located, but it is not where life is sustained directly.
