Solution
The correct option is A Oceans
The CO2 present in the oceans in the form of dissolved gas or carbonates is estimated about 11.2 X 1014 tonnes which is more than 50 times of the amount present in the atmosphere.
Green plants fix about 70-80 billion tonnes of CO2 annually by the process of photosynthesis. Out of total CO2 fixed, 90% is fixed by water plants (mainly in oceans) than 10 % fixed by terrestrial plants.
Hence, the correct answer is 'Oceans'.
