Hint: Sometimes in order to warn the predator to prevent them from getting preyed upon, certain animals change their color to brighter forms so that they can easily be spotted and warn prey for not eating them.
Complete Answer:
Warning colouration which is also called as aposematic coloration, is a process in which certain small animals that are poisonous in nature color themselves in order to protect themselves from predators. These prey releases certain poisonous chemicals to protect themselves. Additionally these bright colors help the predators to spot the prey. Whenever these predators eat these animals, they release certain poisonous chemicals that either kills the prey or warns them for their next time. So with these bright colors, the predators tend to remember these animals and do not catch them.
Let us analyse the options to find out the correct option.
Option A: Chameleons are the class of old world lizards which have the capability to change their color according to the surroundings and temperatures. The property of changing colors like this is called camouflage in which they either change their color in response to temperature, communicate with other chameleons, show their behaviour or protect themselves from the prey by matching with the background. Therefore, this is the incorrect option.
Option B: Dart frogs are brightly colored small organisms that have different skin colors. They have the presence of poisonous chemicals within their skin that is harmful for the predator and can sometimes kill the predators too. They change their colors in order to warn the predator against them.Therefore, this is the correct option.
Option C: Praying mantis share the same phenomenon of camouflage as they also change the colors in order to protect themselves from the predator. However, the change in their color is very light.Therefore, this is the incorrect option.
Option D: Stick insects also show the phenomenon of camouflage which helps them to protect themselves from predators.Therefore, this is the incorrect option.
Thus, the correct option is B) Dart frogs.
Note: Warning coloration is found in various animals including insects, mites and spiders. They warn the predators in a single time about how toxic they are and that the predators should avoid eating them.
