Reflex
C
Conditioning
D
Learned
Explanation: 

Detailed explanation-1: -A reflex is an involuntary (say: in-VAHL-un-ter-ee), or automatic, action that your body does in response to something-without you even having to think about it. You don’t decide to kick your leg, it just kicks. There are many types of reflexes and every healthy person has them. In fact, we’re born with most of them.

Detailed explanation-2: -Contact with the cornea initiates 2 reflexes: blink reflex (corneal reflex) and tear production. The corneal blink reflex is caused by a loop between the trigeminal sensory nerves and the facial motor (VII) nerve innervation of the orbicularis oculi muscles.

Detailed explanation-3: -A reflex occurs via neural pathways in the nervous system called reflex arcs. A stimulus initiates a neural signal, which is carried to a synapse. The signal is then transferred across the synapse to a motor neuron which evokes a target response.
