pupillary light reflex is controlled by parasympathetic branch of Autonomous nervous system
Pupillary light reflex is autonomic.
The division of autonomic nervous system responsible for pupillary light reflex is the parasympathetic system. This is what causes the pupils to close down or open up in response to lighting conditions.

The ciliospinal reflex and the pupillary light reflex are classified as autonomic reflexes.
The parasympathetic nervous system stimulates salivary gland secretion, and accelerates peristalsis, so, in keeping with the rest and digest functions, appropriate PNS activity mediates digestion of food and indirectly, the absorption of nutrients.

central.somatic and autonomic nervous systems
While pupillary size in principle is controlled both by the sympathetic and the parasympathic nervous system, the typical closure of the pupil after illumination (i.e. the pupillary light reflex) is mediated by the parasympathetic innervation of the constrictor muscle of the pupil.
The gag reflex is an involuntary reflex, therefore it is an autonomic reflex. The peripheral nervous system is the part of the nervous system outside the central nervous system (which consists of the brain and spinal cord). The peripheral nervous system is split into two parts - the somatic nervous system and the autonomic system. The somatic system controls voluntary skeletal muscle movements and the autonomic system controls involuntary or automatic actions.
Yes. You are right. Most probably nausea is mediated through autonomic nervous system.
The receptor is the retina of the eye; smooth muscle of the iris is the effector. They both change simultaneously because the pupillary light reflex is contralateral.
