The first alternative is true (A).
For some linguists, language is innate, that is to say that men are already born with the ability to communicate linguistically. The greatest prepulsor of this theory is Noam Chomsky, who argues that the human capacity to communicate is grounded in rationality. According to Chomsky, there is a relationship between thought and language. Once man is rational, of course he will develop a form of communication, which will be the language. That is why language is innate to man.
