Correct Answer: The process of capturing and storing carbon dioxide

Solution : The correct answer is (A) The process of capturing and storing carbon dioxide

The concept of "carbon sequestration" refers to the process of capturing carbon dioxide (CO2) from the atmosphere or other sources and storing it in a way that prevents its release back into the atmosphere. This process helps to mitigate climate change by reducing the concentration of greenhouse gases, specifically CO2, in the atmosphere.

Carbon sequestration can occur naturally through processes such as photosynthesis, where plants absorb CO2 and store carbon in their tissues. It can also be achieved through technological methods, such as carbon capture and storage (CCS), where CO2 emissions from power plants or industrial processes are captured and stored underground or in other long-term storage facilities.

The goal of carbon sequestration is to reduce the amount of CO2 in the atmosphere, as it is a major contributor to global warming and climate change. By capturing and storing carbon dioxide, it helps to mitigate the impacts of greenhouse gas emissions and work towards a more sustainable and low-carbon future.
