select the correct answer.
why do mountainous regions have a smaller population?
a. governments prohibit humans from living there because of landslides.
b. the cost of building roads is high when compared to other regions.
c. the quality of the soil limits the amount of food that can be grown.
d. mountain regions face environmental problems, making them unfit for living.

Explanation:

Mountainous regions often have thin, nutrient-poor soil due to steep slopes and erosion, which constrains agricultural productivity. This limits food supply, making it harder to support large populations—unlike options A (not universally true), B (a secondary issue), or D (overly broad, as some mountain areas are habitable). Soil quality directly impacts basic sustenance, a key factor in population size.

Answer:

C. The quality of the soil limits the amount of food that can be grown.
