Answer:
d. A dog blinks its eyes after a flash of light is presented.
Explanation:
Since a dog blinks the eyes involuntarily, this is a simple example of non-conditioned and is a natural reaction.
It is an action out of a reflex, a response to a stimulus.
Reflexes are involuntary and occur nearly immediately in response to determinate stimulus automatically. It does not receive any conscious thought.
To the contrary, operant behavior requires a process of learning through conditioning.
