Explanation:

In the somatosensory system's neural integration, the circuit level involves processing in the spinal cord (and brain stem) where sensory information is integrated into pathways. The receptor level is about sensory receptors, perceptual is in the cerebral cortex, and integrative isn't a main level here. So the correct option is the one related to spinal cord processing, which is circuit level.

Answer:

D. circuit level
