Changes in the energy balance between the oceans and atmosphere play an important role in the planet's climate change. The circulation of the oceans is affected by variations in atmospheric circulation. Surface currents are driven by the force of the wind pushing on the ocean surface. The frictional drag of the wind on the surface layer of the ocean creates currents. The wind also mixes surface waters creating what is called the mixed layer, where there is little vertical temperature change.
Fossil Fuel emission affect oceans in several way, as it increases carbon dioxide in it, thus acidifies it, and as organisms trap this gas, their carbonate (on their body) decreases. In short, Your Answer would be Option D. Hope this helps!
