Answer:
The process responsible for the formation of deep sedimentary basins, where oil deposits form, is known as sedimentation.
Step-by-step explanation:
Sedimentation is the process of accumulating and depositing sediments. Sediments can include various materials like minerals, rocks, and organic matter. When sediments accumulate in a basin over time, they can compress and cement together to form sedimentary rocks like sandstone, shale, and limestone. The pressure and heat from the weight of the overlying sediment can also cause organic matter to transform into fossil fuels like oil and natural gas. Therefore, it is sedimentation that is responsible for the formation of deep sedimentary basins where oil deposits form.
