Final Answer :
B
Explanation :
A normal response for the diagnostic positions test is parallel tracking of the object with both eyes. Eye movement that is not parallel indicates a weakness of an extraocular muscle or dysfunction of the CN that innervates it. The diagnostic positions test assesses for any muscle weakness during movement of the eye by leading the eyes through the six cardinal positions of gaze. It is not assessing the ability of the eyes to converge, or move toward each other. Nystagmus with an extreme superior gaze is normal, but not in any other position and lid lag is not normal.
