In classical conditioning, the unconditioned stimulus (UCS) is the stimulus that naturally and automatically triggers a response, without any conditioning. In this experiment, the puff of air to the rabbit's eye is the UCS because it naturally elicits a blink reflex.

Therefore, option B is the correct answer.
