B
found mostly in Africa
C
a forest biome dominated by coniferous trees, such as pine, fir, and spruce
D
a dry, rocky biome found in the central part of South America.
Explanation: 

Detailed explanation-1: -Vegetation: Needleleaf, coniferous (gymnosperm) trees are the dominant plants of the taiga biome. A very few species in four main genera are found: the evergreen spruce (Picea), fir (Abies), and pine (Pinus), and the deciduous larch or tamarack (Larix).

Detailed explanation-2: -The coniferous forest biome is usually called the taiga or boreal forest. This forest is dominated by large coniferous trees (trees that produce cones instead of flowers), such are pine, spruce, and fir.

Detailed explanation-3: -taiga, also called boreal forest, biome (major life zone) of vegetation composed primarily of cone-bearing needle-leaved or scale-leaved evergreen trees, found in northern circumpolar forested regions characterized by long winters and moderate to high annual precipitation.

Detailed explanation-4: -The taiga is sometimes called the coniferous or boreal forest. Coniferous forests are found in northern Canada, Asia, and Europe. Coniferous forests are also found at high altitudes in the United States. In New Hampshire, coniferous forests are found in the White Mountains.
