Answer:
(b) Congo Basin
Explanation:
The Congo Basin in Central Africa is home to the world's largest tropical peatland, known as the Cuvette Centrale peatlands. These peatlands store a massive amount of carbon, estimated to be equivalent to three years' worth of global carbon emissions from fossil fuels. The preservation of these peatlands is crucial because their destruction could release significant amounts of carbon dioxide into the atmosphere, exacerbating global climate change.
