Option D — Carbon sink: It is reduces the fraction of emissions remaining in the atmosphere and is associated with a sink can weaken if ecosystems are degraded. Exam Takeaway: Link Tropospheric ozone with “contributes to warming near Earth's surface” and “it should not be confused with protective stratospheric ozone” for quick revision.
