ANSWER: D paralysis on same side = left lesion, level upto umbilicus
Brown-Séquard syndrome is caused by damage to one half of the spinal cord, resulting in paralysis and loss of proprioception on the same (or ipsilateral) side as the injury or lesion, and loss of pain and temperature sensation on the opposite (or contralateral) side as the lesion.
