Answer:
Hello,
The answer would be A,
Some animals can change their appearance to stay safe.
The text provided says that the animals change their appearances to avoid getting eaten by predators. It says " Some fish puff up their bodies to scare other animals away. Some frogs change how their skin looks to blend into their surroundings and avoid predators. Many octopuses can make themselves look like other animals to avoid being hunted."
This shows they are just trying to survive.
Therefore, the answer would be A,
Some animals can change their appearance to stay safe.
Hope this helps! :)
