There are many parts of the peripheral nervous system, but options are not listed below.
I will use my best prediction using deductive reasoning to proves which is part of the PNS - peripheral nervous system.
The peripheral nervous system is defined as a bundle of neurons, that is neither the brain or spine (which is in the CNS - central nervous system)
As you may know the PNS, is broken down into two pieces.
The autonomic and somatic nervous system.
The autonomic nervous system as you may know is the part of the PNS, that controls involuntary activities. e.x breathing, heartrate, blood pressure, temperature, etc.
The somatic nervous system on the other hand is voluntary, and is associated with the feelings of the body. (heat, cold, touch, smell)
The first one should be "Fight or Flight". I'm not sure about the second one.
