People who have a severed corpus callosum are likely to have difficulty:
a. planning for an upcoming holiday, because the "executive control" area of the brain has been damaged
b. tracking the direction and speed of objects in motion, because the visual area of their brain has been damaged
c. writing a poem, because the speech area of their brain has been damaged
d. coordinating speech and action across left and right sides of the body, because the connecting part of the brain has been damaged

The correct option is D

Explanation:

People with a severed corpus callosum would have a disconnection between the two sides of the neocortex, their conscious thought, and usually have difficulties in movement control. A severed corpus callosum simply means that the corpus callosum has been sliced during an operation and thus such person would have issues coordinating speech as there would be a disconnection in their home of language and any action between the two parts of the body, including body movements.
