Answer:
Eye blinking after a flash of light is presented
Explanation:
Blinking your eyes after seeing a ray of light is not a behaviour derived from operant conditioning, because the action was not carried out because of its association with some sort of reward or punish.
On the opposite, the blinking of the eye is carried out automatically, as a biological response deeply engrained in our brains, which is not fully conscious, and has the goal of protecting the eye against the light. For this reason, this type of behaviour could be classified as reflexive instead of conditioned.
