Final answer:
The dorsal column system carries touch and proprioception information, while the spinothalamic tract carries pain and temperature sensation.
Step-by-step explanation:
The two major tracts in the spinal cord, the dorsal column system and the spinothalamic tract, carry different types of information and have different pathways in the body. The dorsal column system carries touch and proprioception information from below the neck to the brain, while the spinothalamic tract carries pain and temperature sensation from the body to the brain. So, option b) is the correct answer.
