    D2 only

    Answer:

    C. 1 only

    Read Explanation:

    • The Food and Agriculture Organization (FAO) defines a forest as land occupying more than 0.5 hectares with trees higher than 5 meters and a canopy cover of more than 10 percent, or trees able to reach these thresholds in situ (It does not include land that is predominantly under agricultural or urban land use).

    • According to FAO and UNEP forests covered 4.06 billion hectares or approximately 31 percent of the global land area in 2020 (though they are not equally distributed around the globe)

    • The UNESCO defines grassland as land covered with herbaceous plants with less than 10 percent trees and shrub cover.
