Which reason best explains what areas of south Asia with arid climates aren’t densely populated

1. Limited access to water: Arid regions in South Asia often face scarcity of water resources, making it challenging for people to settle in these areas due to lack of access to sufficient water for drinking, agriculture, and other basic needs.

2. Harsh environmental conditions: Arid climates in South Asia often experience extreme temperatures, limited vegetation, and harsh living conditions, making it difficult for people to sustain a livelihood in these areas.

3. Lack of infrastructure and development: Arid regions in South Asia may lack basic infrastructure such as roads, schools, hospitals, and other essential services, making it less attractive for people to live in these areas.

4. Limited economic opportunities: Arid climates may not support diverse economic activities, limiting opportunities for employment and livelihoods in these regions, leading to lower population density.
