The reservoir that has the largest deposit of carbon is the oceans.

To determine which reservoir has the largest deposit of carbon, we need to look at the global carbon cycle. The carbon cycle represents the movement of carbon between various reservoirs on Earth, including the atmosphere, plant biomass, rocks and sediment, and oceans.

To answer this question, we can consult scientific data and estimates provided by climate scientists and researchers.

One commonly accepted estimate is that the Earth's oceans hold the largest deposit of carbon among the listed options. The oceans are estimated to contain approximately 50 times more carbon than the atmosphere, 10 times more carbon than plant biomass, and 1,000 times more carbon than rocks and sediment.

This estimation is based on the fact that carbon is dissolved in the ocean, primarily as dissolved inorganic carbon (DIC) in the form of bicarbonate and carbonate ions. Additionally, the oceans contain large amounts of organic carbon in the form of marine plants and animals.

So, in summary, the correct answer is the oceans, based on scientific estimates of the global carbon cycle.
