Answer:
A) Turkey feet grass
Step-by-step explanation:
Grassland biome is one of the biomes that makes up the Earth's biosphere. Due to the characteristics of this biome (grassland), it favours the abundance of grass species over trees and shrubby plants. These characteristics include a low annual rainfall, soil's susceptibility to wind erosion etc.
Based on these characteristics, an organism that will thrive in this biome must be structurally adapted to it. This is the case of the Turkey feet grass mentioned in the question. The Turkey feet grass possess very deep roots to prevent soil loss in windy areas, and to help anchor the plant. This is as a result of soil loss common to the soil of grassland biomes.
