Answer:
Option (2)
Explanation:
Lithosphere refers to all the portions on earth where life exists. In simple words, the lithosphere is the layer that is comprised of the crust and a small portion of the upper mantle. Here the rocks are solid in nature.
Biosphere refers to the region that includes the land surfaces, hydrosphere as well as the atmosphere in which life exists and interacts. It occurs both above and below the earth's surface.
The rocks are disintegrated by both physical and chemical processes. These rocks when they are broken apart into smaller particles, then these sediments or rock particles are deposited in the soil that provides the necessary materials for the plants to grow.
Thus, the two spheres with which it interacts are the lithosphere and the biosphere.
Hence, the correct answer is option (2).
