The correct answer is C. natural stratigraphy.
An anticline is a fold in the Earth’s crust that is convex upward. Faults are fractures in the Earth’s crust along which there has been movement. Synclines are folds in the Earth’s crust that are concave upward. Natural stratigraphy is the layering of rocks in the Earth’s crust.
Oil and gas are formed from the remains of ancient plants and animals that have been buried and subjected to heat and pressure over millions of years. These hydrocarbons are trapped in porous rocks, such as sandstone, that are overlain by impermeable rocks, such as shale. Anticlines and faults are common traps for oil and gas, as they provide a way for the hydrocarbons to migrate to the surface. Synclines, on the other hand, are not as likely to contain oil and gas, as they do not provide a way for the hydrocarbons to migrate to the surface.
In addition, natural stratigraphy is not a type of trap that can hold oil and gas. It is simply the layering of rocks in the Earth’s crust. This layering can be caused by a variety of factors, such as sedimentation, erosion, and tectonic activity. However, it does not provide a way for oil and gas to migrate to the surface and become trapped.
