Correct Answer:
B. A place where carbon is stored away from the atmosphere
Explanation:
A carbon sink is defined as any natural or artificial system that absorbs and stores more carbon dioxide from the atmosphere than it emits. By capturing greenhouse gases through processes like photosynthesis in forests or absorption in oceans, these sinks play a crucial role in mitigating climate change and stabilizing global temperatures. Common examples include woodland ecosystems, soil, and marine environments, which act as reservoirs that effectively remove carbon from the natural cycle for extended periods.
