The answer that makes the most sense here is A. instinct.
The cat does not have a reflex that makes her run away, nor is it conditioned.
It is not conditioned because she is not influencing herself to run away, sure she is changing the outcome but that would only change if she ran away once. Because she continues doing it the outcome isn’t really changing.
She is not imprinting, because imprinting is when an animal forms attachments.
Therefore she has an instinct to run away and hide whenever her owner pulls out the carrier.
I hope that this is correct and that it helps you! :)
