D. Since she has returned from war, Regina has been having nightmares and is startled by every sound, believing she is in imminent danger.
Explanation:
Post traumatic stress disorder (PTSD) is a condition that is experienced by someone who has undergone some sort of trauma. The trauma could be something that they have witnessed or experienced themselves, like natural disasters, war, or a serious accident. 
Although not all people come out of a traumatic event with PTSD, those who do are those who are not able to or having difficulty with coping and adjusting to life after the trauma. 
Symptoms and intensity of the symptoms vary depending on the trauma they experienced and the general mental health of the person. Some of the most common ones would be avoidance, anxiety, night terrors, and the like. 
 
        
             
        
        
        
Answer: Motor neuron effector
If you accidentally touch hot surface, you automatically
pull your hand away from the object and this response is governed by a simple
combination of neurons called reflex arcs. The sensory neurons carriers the
impulse towards the central nervous system (CNS) then the interneuron carries
these impulses within the CNS, while the motor neuron carries impulse away from
CNS. Therefore, motor neuron is the last structure to respond to a reflex.
