Explanation
The biosphere hospitable to life is known as (B) Eubiosphere.
The term “eubiosphere” refers to the part of the biosphere that is hospitable to life, where living organisms can thrive. The biosphere is the global sum of all ecosystems and includes all living organisms on Earth, as well as the non-living components of the environment with which they interact, such as air, water, and soil. The eubiosphere is a subset of the biosphere that includes only those regions where conditions are favorable for life.
