Explanation:

The text does not provide information about what the male glass - frog does first when another male comes to its area. However, we can eliminate options that are not logical. It is unlikely to give its eggs to another male, and leaving the area is not a typical first - response. Fighting is mentioned as something that may happen later. Making a loud warning sound is a common first defensive behavior in many animals.

Answer:

It makes a loud warning sound.
