A cantilever beam of length \( L \) is fixed at one end and carries a concentrated downward load \( P \) at its midpoint together with an applied moment \( M = PL/2 \) at the free end, as shown in the figure.
Neglecting the self weight of the beam, which one of the following options correctly shows the shear force diagram (SFD) and the bending moment diagram (BMD) for this beam?
