Ans) a
Exp) Option a is correct.
Blue Carbon refers to coastal, aquatic and marine carbon sinks held by vegetation, marine organisms and sediments. The coastal ecosystems of mangroves, tidal marshes and seagrass meadows contain large stores of carbon deposited by vegetation and various natural processes over centuries.
These ecosystems sequester and store more carbon – often referred to as ‘blue carbon’ – per unit area than terrestrial forests. The ability of these vegetated ecosystems to remove carbon dioxide (CO2) from the atmosphere makes them significant net carbon sinks, and they are now being recognised for their role in mitigating climate change.
