Which pair of setback distances is correct for fish-bearing streams versus non-fish streams?

Explanation:
Setback distances create a buffer around streams to keep pesticides out of the water and protect aquatic life. Streams that support fish are more sensitive to pesticide drift and runoff, so they require a larger buffer to reduce exposure. The correct pairing is 75 feet for fish-bearing streams and 50 feet for non-fish streams. This arrangement gives extra protection where fish live while keeping a practical minimum setback for other streams. Other options either don’t provide the extra protection for fish-bearing streams or misstate the required distances.
