@tomgbean, happy to help.

(D) states that "hatchery-raised fish that are released into the wild need to eat many different types of food to survive."

The passage does not necessarily point to hatchery-raised fish needing to eat many different types of food to survive, but instead to them possibly needing to be bold in exploring new types of food. Perhaps these fish only need to eat one type of food to survive, but first have to figure out what that food is. Some fish may find this food source right away without trying other foods, whereas others may need to forage new types of food to find it. If those fish are not bold enough to forage through different food types to find it, they will likely not survive.

This distinction supports (C) and shows that (D) is an unnecessary assumption.

Does that make sense? Please let us know if you have any other questions and best of luck with your studies!
