• A. Renewable Resource
• B. Oil
• C. Natural Gas
• D. Environment

Answer: (B)

Petroleum is oil, a fossil fuel formed from ancient organic matter that was buried and transformed by heat and pressure in sedimentary rocks deep within the Earth. Because this formation happens over millions of years, the amount available is finite and cannot be replenished on human timescales, making it nonrenewable. The phrase “geologic structures within the Earth” refers to underground oil reservoirs trapped by rock layers, which is why oil is described this way. The other options don’t fit: a renewable resource is something replenished quickly, environment is not an energy source, and natural gas is another fossil fuel but not the substance commonly called petroleum.
