The correct option is B Tundra
A biome contains several plants and animals that have similar characteristics due to the climatic conditions prevailing there. In tundra biome, the short season and low temperatures act as an obstacle to the growth of the plants. Tundra is the coldest of all the biomes. There are three types of tundra: arctic tundra, alpine tundra, and antarctic tundra. In tundra, the vegetation is composed of dwarf shrubs, sedges, and grasses, mosses, and lichens. Scattered trees grow in some tundra regions. The ecotone between the tundra and the forest is known as the tree line or timber line. These biomes have evergreen trees and animals adapted to drought.
