The correct answer is C. Crude oil is found today under both dry land and the ocean. When crude oil forms, it accumulates in porous rocks like sandstone or limestone, creating underground reservoirs. These reservoirs can be located beneath the Earth's surface, on land, or beneath the ocean floor.
To determine the answer, we can use our knowledge of the formation of crude oil. Crude oil is formed over millions of years from the remains of marine organisms like plankton, algae, and bacteria. These organisms died and settled on the ocean floor, where layers of sediment covered them. As the layers of sediment built up, the organic remains were subjected to heat and pressure, resulting in the formation of crude oil.
Because the source of crude oil is primarily marine organisms, it is found in areas where these organisms lived or where their remains were buried. This includes both underwater sedimentary basins and areas of dry land with ancient seabeds. Therefore, crude oil can be found under the ocean as well as beneath dry land, making option C the correct choice.
