Answer:

b. in sensitive periods that differ across species.
Explanation:
Imprinting happens when an animal (or a human being) learns and recognizes the characteristics of a stimulus. The most common example is filial imprinting observed in goslings. They will imprint in any animal, human, or even inanimate object placed before them during a critical sensitive period. They soon begin to follow that animal, human, or object around, as if it were their mother. In the case of goslings, that can happen until up to 16 hours after birth. However, that period changes across species.
