Final answer:

b) Dorsal Column-Medial Lemniscus Pathway. The spinal cord tract for light touch and pressure is the Dorsal Column-Medial Lemniscus Pathway.

Step-by-step explanation:

The spinal cord tract for light touch and pressure is the Dorsal Column-Medial Lemniscus Pathway (option b).

The dorsal column pathway is responsible for conveying fine touch, vibration, and proprioceptive information, while the spinothalamic pathway primarily conveys pain and temperature.

In the dorsal column pathway, the information ascends ipsilateral to the stimulus source and decussates (crosses over) in the medulla. On the other hand, the spinothalamic pathway decussates at the level of entry and ascends contralaterally.
