Final Answer : B, Explanation :  In split-brain patients, the corpus callosum, which connects the two hemispheres of the brain, is severed. This means that information received in one hemisphere cannot be easily shared with the other. Since the language center is typically located in the left hemisphere, and the left hand is controlled by the right hemisphere, a split-brain patient would not be able to verbally identify an object placed in their left hand because the sensory information cannot be relayed to the language center in the left hemisphere.
