Five-Year-Old Lucy Encounters the Word Platypus in One of Her

Five-year-old Lucy encounters the word platypus in one of her storybooks and asks her father what the word means. When her father tells her that a platypus is a kind of animal, Lucy has an easier time learning what a platypus is than she might have otherwise. A cognitive psychologist would be most likely to explain this by saying that:

A) Lucy is now able to form a script regarding the nature of a platypus.
B) Lucy's personal theory about the nature of living things helps her narrow down the possible defining features of the concept platypus.
C) The father's statement makes it unnecessary for Lucy to form a prototype of the concept platypus.
D) The father's statement enables Lucy to develop a variety of exemplars that illustrate the concept platypus.
