Answer:
D - She pities them and sees them as animals struggling to survive.
Step-by-step explanation:
"One by one, they would stalk the defenseless fish..."
"Not a moment later, they'd break through the surface with a poor fish flailing and fighting for its life only to carry it away and bring it to its final demise...."
She pities them. She understands that they are animals fighting and struggling to survive, but pities the situation of something, someone, putting and end to your life just like that. In that moment the fish is being hunted, but something else could hunt the ospreys. It would be the same situation.
