Question

which action can help reduce mudslides?○ planting trees○ restricting farming○ building dams○ increasing irrigation

Explanation:

Tree roots bind soil particles together, reducing soil erosion and the likelihood of mudslides by stabilizing slopes. Restricting farming is not a targeted or necessary action for most areas, building dams primarily manage water flow/ flooding not slope stability, and increasing irrigation can weaken soil structure and increase mudslide risk.

Answer:

planting trees
