The right answer is D. spinal cord, thalamus, somatosensory cortex.
To summarize, sensations are sensed by sensory receptors. These sensations are transmitted by the axon of the receiver to the spinal cord or a cerebral nucleus, before reaching the thalamus. After the relay in the thalamus, the sensations are transmitted to the sensory cortex, which processes this information. Only the sense of smell goes against the thalamus and reaches the brain directly.
