{'biosphere': [3, 0, 0, 1], 'hydrosphere': [4, 0, 0, 0], 'living matter': [1, 0, 0, 0], 'lithosphere': [0, 0, 0, 1], 'sphere': [2, 0, 8, 5], 'earth': [0, 1, 1, 1], 'soil': [7, 0, 4, 7], 'atmosphere': [1, 1, 4, 7], 'surface': [1, 0, 0, 0], 'water': [65, 15, 80, 129], 'air': [1, 0, 0, 0]}

The correct answer is option 2: Biosphere. The biosphere refers to the sphere of living matter, which includes all living organisms on Earth along with the surrounding water, air, and soil. It is the zone where life exists and thrives.

Option 1: Lithosphere refers to the solid, outer portion of the Earth, including the crust and upper mantle. It does not encompass the living organisms.

Option 3: Hydrosphere refers to all the water on Earth, including oceans, lakes, rivers, groundwater, and water vapor in the atmosphere. It does not include living organisms.

Option 4: Atmosphere refers to the layer of gases that surround the Earth. It includes the air we breathe and extends up to several hundred kilometers above the surface. While the atmosphere does interact with living organisms, it does not include the entirety of the biosphere.
