I agree with you @Amit Choudhary.

The Answer should be Zero as on the neutral axis radius will be zero so shear stress will also be zero.

I think C is the right answer.

Maximum is the right answer.

Why max is measured from the top or bottom fibre. Shear stress is max. At the centre and min. At the top and bottom fibre.

Answer should be None.
Only in pure bending stress or something else alone(Centrod = N.A). It is generally told so it may not always the case.
Correct answer D.None.

At neutral axis, there is no stress of any kind. Then how maximum?

Shear stress = F/2I (d^2/4-y^2) where, F= shear force, I= moment of inertia, d= depth of beam, y= distance from the neutral axis.
So, the maximum shear stress occurs at the neutral axis and is zero at both the top and bottom surface of the beam.
So, the maximum shear stress occurs at the neutral axis and is zero at both the top and bottom surface of the beam.

Shear stress is zero in neutral axis and B.M is maximum are called as neutral axis.

Shear stress is zero at centre and maximum at outermost fibre/ edge.
