Oceans

The correct option is A.
Explanation of correct option:

1. Most of the carbon component is found in the form of biomolecules in the living organism.
2. Since most of the living organism is found in the ocean, the carbon percentage present in the ocean are significantly higher than in other places.
3. Carbon in the ocean is found in the form of-
   1. Biomolecule in planktons and aquatic animals,
   2. Carbonate in corals and seashells,
   3. In coral reefs (habitat of corals),
   4. Dissolved carbon dioxide in the ocean.

Explanation of incorrect options:

Option B

Agroecosystems contain less than 10% of global carbon.

Option C

Grasslands have almost 12% of the carbon available in our ecosystem.

Option D

Forests contain less than 10% of global carbon

Final answer

About 70% of total global carbon is found in Ocean.
