C. Theory of Biogenesis
D. Naturalistic Theory

Answer 1

Hint: This thought was proposed by Richter in 1865 and upheld by Arrhenius (1908) and other contemporary researchers. The theory didn't uphold any proof and needed evidence, hence it was discarded.

Complete answer:.
One possibility that drifts on this outskirt is the panspermia hypothesis, which proposes that life on Earth didn't begin on our planet, but was transported here from somewhere else in the universe. While this thought may appear to be straight out of a sci-fi novel, some proof recommends that an extraterrestrial cause of life may not be such an out of sight.
As indicated by this hypothesis, life has arrived at this planet Earth from other eminent bodies, for example, shooting stars, as exceptionally obstruction spores of certain living beings. The hypothesis didn't support any evidence and needs proof, subsequently, it was disposed of.
The cosmozoic hypothesis is additionally called a theory of panspermia.

Hence, Option (A) is the correct answer.

Additional Information: However, with the goal for life to begin somewhere else known to man, there would need to be a situation on another planet equipped for supporting it. Our investigation of the universe recommends that life as we probably are aware it would struggle to get by outside of the Earth.

Note: In any case, note that life on Earth can withstand numerous extraordinary conditions. A few microscopic organisms develop at temperatures as high as 113°C. At the opposite end, bacteria can flourish at temperatures as low as - 18°C; many can be preserved in fluid nitrogen at - 196°C.
They can likewise endure high portions of ionizing and UV radiation, outrageous weight, and so forth. These perceptions propose that it is hard to characterize the conditions that favor life and make it harder for us to foresee that life is special to Earth.
