ACreate recreational trail systems
BFilter agricultural runoff and protect water quality✓ Correct
CProvide habitat for commercial hunting and fishing
DReduce flooding by slowing water flow only

Explanation

Minnesota's buffer strip law (MN Stat. 103F.48) requires 50-foot perennial vegetation buffers along public waters and 16.5-foot buffers along public ditches on agricultural land. The primary goal is to filter nitrogen, phosphorus, and sediment from agricultural runoff before it reaches waterways. This protects Minnesota's lakes, rivers, and groundwater quality.
