Linear is correct because if we consider its self-weight as udl then for finding sfd and bmd by external loads we must consider its self-weight also and give its effect combined with udl.

Yes, linear is correct.

Linear is correct. In any problems we are not considering the self weight while calculating sf and bm. Self weight of beam is neglected.

@All.
No, parabola is not a correct answer. Linear is correct.

We know that self-weight is UDL and UDL BM is parabola.
Here, the answer is the parabola (when self-weight should be considered) or it must be linear (when self-weight should not be considered).

Here there is no load acting on the beam.
So there is no upward force and downward force on the beam (self-weight is neglected) so BM variation is "Zeo (0) ".
