Final Answer : E, Explanation :  Oil and gas are less dense than water, which causes them to rise toward the surface. They flow most easily through rocks that have high permeability, such as sandstone. Their ascent can be halted by impermeable rock layers, which trap them and form reservoirs. Therefore, all the statements A, B, C, and D are correct descriptions of the behavior of oil and gas once they are formed.

Once oil and gas are formed, they:

A) rise toward the surface
B) are lighter than water
C) flow most easily through permeable rocks, such as sandstone
D) can be prevented from reaching the surface if they are trapped by impermeable layers
E) all of these
