B….inbvwrtical elemnt moment must be constant, in fixed ends moments must be positive

C is the right answer!
B is correct, as C and D needs a horizontal forece acting on the beam sections in order to have varying horizontal moments

Option c…
Conceptually if one was to visualize this problem as an inverted portal frame supported on 2 cantilever beams, the expected deformed shape would result in a moment distribution similar to option c. Mathematically, the moment diagrams should have gradients on the vertical segments and the horizontal segments near the support.
