Answer: D
The greatest reservoir of carbon among these is the deep ocean.
The deep ocean holds about 37,000 to 38,000 billion tonnes of carbon, mostly as dissolved inorganic carbon (bicarbonate and carbonate ions). That is far more than any other active reservoir of the carbon cycle.
Soils hold about 1,500 to 2,400 billion tonnes, terrestrial biomass about 450 to 650 billion tonnes, and the atmosphere about 850 to 900 billion tonnes today. Only the rocks (sedimentary carbonates and kerogen), which are not among the options, hold more than the deep ocean.
