Concept:The innateness hypothesis states that the ability to acquire language is built into the human brain from birth, not learned through experience alone.
Explanation:This theory, mainly proposed by linguist Noam Chomsky, argues that children are born with a fundamental knowledge of language structures known as universal grammar.
This innate knowledge allows children to learn their native language quickly and correctly despite limited input.
It explains how young children can form grammatically correct sentences without explicit teaching.
The hypothesis rejects behaviorist views that language is only learned through drilling, conditioning, or habit formation.
Option A is wrong because all languages do have grammars and children learn them naturally.
Option B describes behaviorist conditioning, not the innateness hypothesis.
Option D also represents behaviorist habit formation, which the innateness hypothesis contradicts.
Only option C correctly captures the core idea: all human beings possess language knowledge at birth.
Answer:C. It believes that all human beings possess language knowledge at birth.
