Correct Answer: A
Choice A is the best answer. The introductory phrase "Known for their ability to change color" describes specific animals. "Chameleons" is the correct subject.
Choice B is incorrect because "camouflage" is not the animal known for changing color. Choice C is incorrect because "the skin" is not the logical subject described by the plural pronoun "their" in the modifier. Choice D is incorrect because "hiding" is an action, not the animal.
