Answer: D) were destroyed when people settled remote parts of the United States.
Explanation: In a simple sentence, the predicate is the part of the sentence formed by the verb and complements, in this case we have a complex sentence (an independent clause and a dependent clause), to find the predicate in a complex sentence we need to identify the subject, and the predicate will be the rest. In this sentence the subject is "Some bald eagle habitats" so the predicate is "were destroyed when people settled remote parts of the United States."
