Which type of theory best accounts for the apparent rapidity and ease of language acquisition in early childhood

A)  behaviourist 
B)  cognitive 
C)  nativist 
D)  social communication

The nativist theory posits that language acquisition is innate and biologically determined. According to this theory, children are born with a language acquisition device (LAD) that allows them to rapidly and easily learn language. This theory best accounts for the apparent rapidity and ease of language acquisition in early childhood because it suggests that children have an inborn ability to learn language, rather than relying solely on environmental factors or learned behaviors.
