Step-by-step explanation:
The correct answer is C. vision.
Vision is not a somatosensory modality. Somatosensation is the group of sensory modalities associated with touch, proprioception, and interoception. These include pressure, vibration, light touch, tickle, itch, temperature, pain, proprioception, and kinesthesia. Vision, on the other hand, is a sense related to the perception of light and allows us to see the world around us.
