[C]. Radial Nerve
Explanation :-
Holstien Lewis fracture:

  • The radiograph shows a fracture shaft of humerus.
  • The nerve most likely to get damaged is radial nerve, as this nerve is very close to the shaft of humerus
  • Holstein Lewis fracture: Entrapment of radial nerve between fragments in the oblique fracture of distal third of humerus. 
  • Radial nerve, which is fixed to proximal fragment by lateral intermuscular septum, is trapped between fragments when closed reduction is attempted.
