What is blue carbon?
B.Carbon sequestered in forest biomass and agricultural soils
D.Carbon present in atmosphere
C.Carbon contained in petroleum and natural gas
A.Carbon captured by oceans and coastal ecosystems
Correct Answer: Option A
Blue carbon refers to the carbon captured and stored by the world's oceans and coastal ecosystems.
Specifically, sea grasses, mangroves, and salt marshes are highly effective carbon sinks along coastlines.
These coastal systems, despite being smaller than forests, sequester carbon at a significantly faster rate and can store it for millions of years.
Therefore, option (a) is the correct answer.
