Explanation:

Plants' roots hold soil in place on hillsides. Removing them eliminates this anchoring, directly contributing to landslides. Clearing trees doesn't directly increase rainstorm frequency. Human activities often increase fire - risk, not reduce it. And landslides are impacted by human activities.

Answer:

A. Removing plants from hillsides eliminates the root structures that anchor soil.
