Which one of the following is the natural vegetation of South east China?

The natural vegetation of Southeast China is primarily characterized by subtropical broadleaf evergreen forests. These forests, often referred to as Evergreen Broad-Leaved Forests (EBLFs), are the dominant and representative biome in the subtropical zone of East Asia [1]. They typically extend from approximately 22°N to the Yangtze River at 31–33°N. These ecosystems thrive in regions with high rainfall and minimal temperature fluctuations between seasons [4]. While tropical rainforests and monsoon forests exist in the southernmost fringes of China (such as Hainan and southern Yunnan), the vast majority of the Southeast region is covered by the subtropical variety [1][2][3]. These forests are known for their high biodiversity and dense, multi-layered structure, though historical human activities like agriculture and timber harvesting have significantly altered their original distribution [1][4][5].
