B) sensory systems; thalamus; amygdala; hypothalamus; midbrain; brain stem / spinal
C) thalamus; hippocampus; basal ganglia; hypothalamus; brain stem / spinal
D) thalamus; occipital cortex; association cortex; motor cortex; brain stem/spinal
E) thalamus; temporal cortex; association cortex; motor cortex; brain stem / spinal

The input to the fear/anxiety neural circuit begins with sensory systems, which convey information to the thalamus. From there, the signal is sent to the amygdala, which is involved in processing emotional stimuli, particularly fear-related stimuli. The hypothalamus then signals to other brain regions and the body's hormonal system to initiate the stress response. The midbrain is involved in coordinating the response, and the brain stem/spinal cord control physiological responses (such as increased heart rate or respiratory rate) that are associated with the fear/anxiety response. Therefore, choice B includes all the key components of the neural circuit involved in fear/anxiety.
