Yes. You people first read the question. All of said linear is satisfactory if without consider dead loads. If it considers parabola is correct.

Linear is correct. No any load sfd is rectangular than bm is linear.

I think answer is parabola. Self weight of beam is always acts as UDL.

Answer is linear. There is no external load Hence it is liner.

Beams with no external loads are considered as 2D. Therefore, self-weight is not considered. Hence the shape will be linear.

Tell me one thing please when you neglect self-weight than without external loading which type of load acting on the beam so bending moment in the beam is linear?
So, the correct answer is parabolic.
So, the correct answer is parabolic.

No load means its should be inclined in case of BMD.

If no load Bm=0(don't consider self wt). If it's mentioned 'some portion beam' not entire 'beam', then answer is linear.

How will you get linear if no load at all (neglecting self wt)?.
In that case, BM=0. If there is some concentrated Moment then it must be linear (ie constant horizontal line).
