Explanation:

Trout are fish that require high levels of dissolved oxygen in water, while catfish can tolerate lower dissolved oxygen. A pond with high dissolved oxygen will support a successful trout catch, along with healthy catfish. Option B has the largest trout catch, indicating the pond has the highest dissolved oxygen level.

Answer:

B. 4 fish (7.7 kg catfish), 6 fish (17.8 kg trout)
