Final answer:
b) Dorsal Column-Medial Lemniscus Pathway. The Dorsal Column-Medial Lemniscus Pathway is responsible for sensory information for the trunk and lower extremity proprioception, two-point discrimination, and graphesthesia.
Step-by-step explanation:
The tract responsible for sensory information for the trunk and lower extremity proprioception, two-point discrimination, and graphesthesia is the Dorsal Column-Medial Lemniscus Pathway (option b). This pathway carries sensory information from the skin, joints, and muscles of the trunk and lower extremities to the brain.
The anterolateral spinothalamic tract (option a) is responsible for pain and temperature sensation, not proprioception, two-point discrimination, or graphesthesia.
The spinocerebellar tract (option c) is responsible for proprioception, but not for two-point discrimination or graphesthesia.
The corticospinal tract (option d) is responsible for voluntary motor control, not sensory information.
