Answer:
Robins have the most beautiful songs of any songbirds
Explanation:
The difference between subjective and objective statement is that, the former is an opinion, while the latter is a fact.
The statement "Robins have the most beautiful songs of any songbirds" is a subjective statement because the songs of a Robin may be beautiful to one person but not to another i.e., it is an opinion shared by a person.
The other three statements are facts and are not opinions of a person.
