A
Ipsilateral Pyramidal Tract Features
B
Contralateral Spinothalamic Tract Features
C
Contralateral Posterior Column Features
D
Ipsilateral Planter Extensor
High-Yield Explanation
Answer is C (Contralateral Posterior Column Features): Brown-Sequard Syndrome (Hemisection of spinal cord) is characterized by lesions of the ipsilateral posterior column (and not contralateral posterior column). The_pvramidal tract (coicospinal tract) is involved on the same side (ipsilateral pyramidal tract features), which also explains the ipsilateral planter extensor response.
