-The following statements concerning this case are correct except which?

A) Occasionally the styloid process of the ulna is also fractured.
B) The median nerve may be injured at the time of the fall.
C) When the fracture is reduced, the styloid process of the radius should come to lie about $0.75 \mathrm{in} .(1.9 \mathrm{~cm})$ proximal to that of the ulna.
D) The fracture produces posterior angulation of the distal fragment of the radius.
E) On reduction of the fracture the distal end of the radius should lie at an angle of $15^{\circ}$ anteriorly.
F) The hand should always be splinted in the position of function.
