Select the correct text in the passage. Which sentence incorrectly describes the formation of petroleum

About 300 million years ago, the seas and oceans were inhabited by tiny plants and other organisms. These organisms died and were buried on the ocean floor. Over time, their bodies were covered with silt and mud that was rich in organic material, forming layers of organic matter. This matter was subjected to high temperature and pressure. In such conditions, oxygen was available in abundance. Over a period of many years, the matter decomposed and formed oil and gas.

Answer is: In such conditions, oxygen was available in abundance.

Because in such conditions there was no or very little oxygen. If there was oxygen the organic matter would not decomposed and formed oil and gas, because there would be reaction of oxidation.

Petroleum is used primarily as a fuel in combustion engines.
