Answer :
Biome that is extremely flat for long distances and has very strong winds is:
D. Temperate grassland
Explanation:
1. Temperate grasslands are characterized by vast expanses of flat terrain with minimal trees, allowing winds to blow freely across the landscape.
2. Strong winds are a common feature in temperate grasslands due to the lack of natural barriers like mountains or dense vegetation that would otherwise obstruct wind flow.
3. Examples of temperate grasslands include the prairies in North America and the steppes in Eurasia, where the flatness of the terrain contributes to the presence of strong winds.
In conclusion, the biome that fits the description of being extremely flat for long distances and having very strong winds is the temperate grassland.
