The Biosphere.

Right.

Yes, the correct answer is c. the biosphere. The biosphere refers to the sum of all ecosystems on Earth, including the living organisms, their habitats, and the interactions between them. It includes all parts of the Earth's surface, as well as the lower atmosphere and the deep oceans, where life exists. The biosphere encompasses not only the land and water but also the atmosphere, making it the correct answer in this case.
