Answer:
D) two species of rattlesnake that both rattle their tails
Explanation:
The Mullerian mimicry can simply be described as a common feature of two or more different species that can be harmful and dangerous in order to fend of predators. In this case we have the two species of rattlesnake which are using the same method to fend of any predators from, by rattling their tails. This is very useful as a defense mechanism because the species that can cause harm to them only need to encounter one of the species and then be wary of both and avoid them both, as both species use the same tactic for defense or warning, thus the chances are reducing even more that an animal, especially a young and inexperienced one, will mess with them or attack them.
