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.

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).
In that case, BM=0. If there is some concentrated Moment then it must be linear (ie constant horizontal line).

In some portion, self wg of member is not considered in calculation so given answer is right.

Here it is asking for BMD and it will not consider self-weight while drawing. So, here BMD will be a straight horizontal line. And in that sense, it is taken as linear.

Here no act loading in this beam so the corect answer is Linear (here self weight of the beam are no prefer).

If the beam having no external load then it would not be bend. So shape always will be liner. And self weight will be act as udl but it does not change the shape because beam carries its weight without any bending.
