Solution
The correct option is B Marine phytoplankton
Most of this oxygen comes from tiny ocean plants – called phytoplankton – that live near the water’s surface and drift with the currents. Like all plants, they photosynthesize – that is, they use sunlight and carbon dioxide to make food. A byproduct of photosynthesis is oxygen.Scientists believe that phytoplankton contributes between 50 to 85 per cent of the oxygen in Earth’s atmosphere.
So the correct option is 'Marine phytoplankton'.
