Quizplus · Accepted Answer

Oil and gas source rocks are formed from the accumulation of organic material in sedimentary basins over long periods of time. Igneous and metamorphic rocks are formed by different processes and do not typically contain the necessary organic material for oil and gas generation. Porosity is a property of rock that relates to its ability to hold fluids, but not all source rocks have high porosity. Therefore, the best choice is B) sedimentary.
