Seven-Year-Old Alfanso Is Going to the Eye Doctor for the First

Seven-year-old Alfanso is going to the eye doctor for the first time. One of the tests performed by the eye doctor is one that checks for pressure in the eye. To take this test, Alfanso sits in a chair, places his forehead against an apparatus, and waits for instructions from the doctor. Then his eye is hit with a puff of air! While it doesn't hurt, it sure is startling and reflexively causes Alfanso to blink. When the doctor says it's time to check the other eye, Alfanso begins to blink as soon as he rests his head against the apparatus. What is the MOST likely explanation for Alfanso's behavior?

A) Alfanso's conditioned response to the air puff generalized the feeling of the apparatus against his forehead.
B) Alfanso acquired a conditioned response to the feeling of the apparatus against his forehead due to its pairing with the air puff.
C) Alfanso's unconditioned response to the air puff extinguished his response to the feeling of the apparatus against his forehead.
D) Alfanso discriminated between the air puff and the feeling of the apparatus against his forehead.
