While it offers compelling explanations for language development, the most significant shortcoming of the nativist account is
a. many of its claims are difficult to falsify.
b. its emphasis on extralinguistic information.
c. the emphasis on neurophysiology.
d. it does not address generatively.

The answer is A). Many of its claims are difficult to falsify

Explanation: The nativist theory is a biologically based theory, which argues that humans are pre-programmed with the innate ability to develop language. Noam Chomsky is a strong advocate for the nativist theory of language development.

Chomsky was known for his radical ideas about children being born with innate or "built-in" language devices. These claims are hard to falsify because there is no way to actually verify if at all human has an innate faculty for language.
