The correct answer is option D) Giraffes.
Giraffes are the only mammal that has no vocal cords. They communicate with each other using a variety of non-verbal sounds such as snorts, grunts, hisses, and whistles. They also use a form of infrasound, which is a sound below the range of human hearing, to communicate with other giraffes over long distances. This is important for their social interactions, including mating and territorial disputes.
