Answer:
The correct answer will be option-The bird songs are analogous traits
Explanation:
Analogous traits are the traits which evolved independently in the unrelated organisms but they perform the same functions.
The analogous traits are derived due to the process of convergence that is to perform the same function depending on the habitat thus, development of analogous traits explains the convergent evolution.
The convergence could be observed not only anatomically but in the behavior as well as the physiology. In the given question, since the unrelated species of bird sing songs with similar qualities shows that the singing trait is an analogous trait.
Thus, the selected option is the correct answer.
