A teacher believes that children are born with grammar rules in their brain and thus they can learn any language. Her approach to language acquisition is aligned with

Correct option is C

Nativists.
The teacher's belief aligns with Nativist theory, particularly Noam Chomsky's ideas, which argue that children are born with an innate ability to learn language. Nativists believe that humans are pre-wired with a language acquisition device (LAD) that allows them to understand and produce language. This perspective holds that while the environment provides exposure to language, the ability to learn and understand it is inherently biological. The teacher's view that children have grammar rules hardwired into their brains reflects the Nativist emphasis on inborn linguistic capabilities.
