The Soviet school's Abiogenic theory claimed that oil could be made without the help of living organisms. Which option represents this theory?

• A. Abyssal Abiogenic Theory
• B. Biogenic Theory
• C. Abiotic Deep Theory
• D. Endogenic Oil Theory

Answer: (A)

This question contrasts abiogenic and biogenic origins of petroleum. The option that fits the description of oil forming without living organisms is the Abyssal Abiogenic Theory, which explicitly states hydrocarbons can originate from inorganic processes deep in the Earth. The “abyssal” part highlights a deep-Earth setting for these reactions, aligning with the idea of formation independent of biological material. The Biogenic Theory, by contrast, holds that oil comes from ancient organic matter transformed over time, so it’s not the correct match. The other two options describe abiotic concepts as well, but they’re not the specific label associated with the Soviet view of an abiogenic origin.
