The answer is incorrect, just shear being zero is not sufficient to tell whether is it maximum or minimum.
We require a derivative of shear force to confirm whether is it max or min.
The correct answer will be E since it can be Max and Min both in this section.

Well said, thanks @Abdul Samad.

Since the question doesn't mention the type of beam, so the anology of zero sf and max bm can't be applied, as it varies depending on type of beam. The correct answer should be when sf is zero bm is constant.

Well said @Abdul Samad.
The right answer is either maximum or minimum.
The right answer is either maximum or minimum.

If the shear force is zero along the section means a member is not subjected to any load. When a member is not subjected to any load then how BMD can be maximum?
Please explain it.
