Answer:
D. rivers
Explanation:
A. is not the right answer. Mountains can help settlements be more protected from the attack, but it's hard to build houses in the mountains and to find fertile land.
B. is not the right answer. Deserts are not a good place to live because of the lack of water and fertile land, so cultures don't develop much in the desert.
C. is not the correct answer. While plains are fine for building settlements, it must be taken into consideration what kind of soil there is and how near is the water.
<u>D. is the right answer. Rivers are one of the most important aspects to take into consideration for survival because they are a source of water, and they are likely near fertile land.</u> When developing a culture, it is also great to have it near the river as you can establish travel and trade via water. Therefore, cultures usually develop near the rivers.
