I got this right because I thought of the cavernous sinus which has CN 3, CN4, CN V1 & V2. Out of all of all the options V2 is the only one that controls upper lip. For option C, pupillary reflex is controlled by CN 2 and 3, and if there is a fracture to the orbital floor the closest to the sinuses to be injured is CN5 (V2). Idk I could be wrong but if you guys agree let me know pls.
