The correct option is B
The savannah is a biome characterized by an arboreal-shrub layer in which the tree canopy has a low coverage, either by small trees or because of their low density, which allows a continuous and generally high herbaceous stratum. It combines characteristics of the forest and pasture. Normally, the savannas are dry zones of transition between forests and semi-deserts. The savannas are located in tropical and subtropical zones, especially with dry tropical climates; although similar temperate ecosystems are also sometimes included under this name. The best-known savannah is the African savannah.
