Which statement is correct regarding language acquisition?

Language acquisition, as distinguished from language learning by Stephen Krashen, is a natural, subconscious, and spontaneous process. Children acquire their first language naturally through exposure to their linguistic environment without formal instruction. It is not consciously learned through rules and drills (that would be language learning, not acquisition). Acquisition happens organically as the child interacts with caregivers and the surrounding speech community. Chomsky's theory of the Language Acquisition Device (LAD) also supports this view that humans are biologically wired to acquire language naturally. Therefore, language acquisition is best described as spontaneous/natural (सहज).
