Answer:
The correct option is oceans and plants
Explanation:
During photosynthesis (a process through which autotrophic plants make there own food), plants breath in carbon dioxide (CO₂) and breath out oxygen. The breathing in of CO₂ helps removes CO₂ from the atmosphere.
Also CO₂ can dissolve in water (ocean) to form carbonic acid. So, when air meets the ocean water, the CO₂ in the air is dissolved in the ocean water thereby reducing the CO₂ content in the air.
