As an oceanographer you need to study either; biology, geology, chemistry, or physics. This is because there are four areas of study when it comes to becoming a oceanographer;
biological – studying marine plants and animals
physical – exploring water temperature, density, wave motion, tides and currents
geological – examining the structure and make-up of the ocean floor
chemical – analysing the chemicals in sea water and the impact of pollutants
Therefore, your answer would be A. Marine Biology, B. Coastal Ecology, C. Astronomy, and E. Meteorology.
Human Anatomy has nothing to do with an oceanographer. :)
