Final answer:
The true statement is that pidgins are languages that form when different societies come into contact and need a system of communication. They are simplified forms of language, and unlike Creoles, which evolve from pidgins, they do not have native speakers.
Step-by-step explanation:
The correct statement among the options provided is D. Languages that form when different societies come into contact and they must devise a system of communication are called pidgins. A pidgin is a simplified form of a language that develops when people who do not share a common language need to communicate, often for trade or business reasons. It lacks native speakers and is not as complex as a Creole language, which can evolve from a pidgin when it becomes the first language of a community. Contrary to the claim in option E, a pidgin has no relation to imitating birds.
It's important to note that pidgin languages can develop in various contexts, not exclusively through war as suggested in option C, and that they differ from lingua francas, which are secondary languages used for communication between distinct language groups. Moreover, Creoles, as mentioned, develop from pidgins and are not a precursor to them, making option B incorrect.
Overall, the development of pidgins and Creoles is a testament to the adaptability of human communication across different cultures and circumstances.
