Reason why the study of life and the study of astronomy are connected.

Answer to Problem 1QP
Option b., c. and e. are correct because, connecting the study of planets and life can help to verify the existence of life on Earth. Also, astrobiology can help in exploring the extreme environment conditions on Earth as well as in terrestrial biosphere.
Explanation of Solution
At some point when both the studies, of life and astronomy are interrelated to each other, it is termed as Astrobiology, the study of the living universe. Therefore, Astronomy provides the context for life on Earth to originate and evolve.
Likewise, terrestrial biosphere observations from extremophilic organisms, to intellect evolution and enlighten our understanding about life chances elsewhere. Astrobiology also involves the search for alien life through in situ observation, solar and extrasolar planetary atmospheres spectroscopy, and the hunt for extra-terrestrial intelligence.
In this way, astrobiology situates within philosophical concern of the meaning of life and the universe. This discusses the habitability of the Universe in general, and planets and moons in particular, and summarizes existing issues in origin-of-life research and evidence of Earth's early life.
Conclusion:
Thus, Option a. is not correct because, as existence of life is not possible at some places like planets, etc. So it can be common between the things existed in the universe.
Option b. is correct because connecting the study of planets and life leads to the verification of the existence of life on Earth, as astronomy and biology are interconnected in the study of Astrobiology.
Option c. is correct as the astrobiology can help in exploring the extreme environment conditions on Earth as well as in terrestrial biosphere.
Option d. is incorrect because life is something that evolved due to various physical processes happened in the nature before, but evidences are found in the early study of life that life on Earth is unique.
Option e. is correct since, astronomer is responsible for the study of life terrestrial and elsewhere. Astronomy provides the context for the origin and evolution of life on Earth.
