Final answer:
Oil, natural gas, and minerals can be extracted from the ocean floor.
Step-by-step explanation:
Oil, natural gas, and minerals can all be extracted from the ocean floor.
Oil is mainly obtained through offshore drilling, where rigs are designed to operate in water as deep as two miles. Natural gas can also be extracted through a process called fracking, in which high-pressure fluids are injected underground to force out the gas. Minerals can be mined from ocean sediments.
Therefore, the correct answer is option D) all of the above.
