The case which shows all the nonzero internal forces at c is
What is a beam?
Beam is structural member which resists transvers load only. if transvers load not acting on the beam then the shear force and bending moment are zero.
The given condition is beam subjected to axial load or horizontal load due to these loads, the reaction forces will act along the axis of the beam only and shear force and bending moment also zero
Hence, the correct option is Option A
