Imprinting is a behavior that includes both innate components and learning components and normally can not be irreversible. It is something that takes place at a specific sensitive period.
For instance, ducklings follow their mother is imprinting that is both innate and learned at a limited phase after birth during development. It can be visual or auditory or other ways that an animal can develop imprinting.
It depends on how you look at evolution. I would say B would be my answer. but it also depends on the course you take. Mine was a Christian based course. So I learned that evolution wasn't a thing.
