Either A or B.. I Would most likely choose A but I'd assume either one
Explanation:
Because a population is the breeding in a specific area.. and Bald Eagles could travel distances from other while fish in a lake would be one area and they would most likely be breeding, as well as the tree one is in a given area, but they don't specifically breed so i'd assume A.
( Also I like your pfp JJK manga and anime is really good )
